how long can hatching eggs survive if left by hen

Hi All, just had a silky hatching some eggs get confused and not go back on her eggs, she is down about 9 days and they were left about one hour, i presume they will not hatch now?

Also discovered the following web site when i was searching for an answer on line, it has great info on hatching in case anyone is in a learning mode like myself.

Thanks as always,

Rj.

Yes they will still hatch. Hatching eggs can be left for up to 10 hours and they will still usually hatch.

if eggs were left everyday for 10 hours and heated for 14 hours, would they still hatch?? or is it only a once off??

10 hours is a bit too long if the weather is cold, 1 to 2 hours at the most, a broody should realy be in a house a pen of her own,so she can sit in peace an not go back to the wrong nest, also watch when eggs are hatching,when the older chicks move ,the hen will follow an leave any eggs still to hatch, happend to me this morning, there was one egg left pipping ,an the hen followed the chicks to the far side of the house, i checked 2hours later an pipping chick had died from the cold.

Thanks Pearl, i converted the kids plastic play house to a nice hatching house but its got 3 hens in it, so i need to keep an eye out for another one that someone wants rid of, in the mean time i think if i do a better job of picking up eggs she will be less likely to get confused. I saw a great hatching house made from a plastic water tank, might try that too.

Thanks a lot everyone.

you could convert an old dog house an make a run for it, i have 6 dog kennels i changed into broodie houses, by not screwing one side of the roof down ,i can lift it to check/clean out, add a removeable run ,an its done!, jumbletown .ie , some times have free kennels.
if you want to see my kennel an run, just pm me your ph number,an i will send pics.

My incubator turned off by accident overnight for around 15 hours.They hatched a few days late but weak and most died in shell

Cochin, i will see about getting a photo, though all i did was put some scraps of ply on the windows and a bit of left over tin as a ridge tile to stop the rain dripping in. I have three hens, a copper marans, cornish and a bantam cross sitting in three egg boxes on a bed of straw, its nice and cosy and in a seperate pen that used to be a dog kennel. now to find a camera and figure ot how to do this...

rjd,when has left the nest and stoped hatching at day 15,the eggs will be good for 4 to 5 days but no longer.they need to be let go cold and dont try to keep warm cos that may kill the chick.you can then at the 4 day stage put them under a new hen NOT an incubater and most if not all will hatch.when the egg is let go cold the half formed chick will just go dorment but if it's late in the hatch it dont work so good.the trick is to just let them go cold.the chicks will be about 6 days late.it can be day 1 2 3 4 or5 it dont matter. good luck

Thanks Benny, i need to print out and save this stuff.....are you saying that this works at only day 15 or up to day 15 and then that you wait for 4 days before resetting?

Many thanks,

Rj.

no,any day up to about 14 15 any later and it dont work so good.the eggs will stay good for up to 5 days,reset any day up to 5 days but it dont work to reset in an incubater,but it will work to reset from incubater to a hen.hope this helps.after 5 days cold they start to rot!

Benny, you are saying that a chick that has been incubated for up to 15 days can then be taken out of incubation and stored cool for up to 5 days, then put under a broody to continue incubation and hatch successfully. Is this correct?
Are you having a laugh? I'll have a look through my books again, but I don't remember ever having read anything of the sort. Maybe maybe if the egg was just a few days along, but I don't believe a 2 week old chick could survive such treatment.

I,ve seen you mention this before Benny,have you done it a lot or just the once,just thinking if it was a one off maybe it was just a fluke,be interested to hear how many times it,s been successful.
Susan i doubt you,ll find any reference to it in a book,maybe wrong though,theres a lot of stuff that works and is discovered through practical experience that is never mentioned in books.

no book will tell you this sort of thing,this is from years of trial and error.a friend of mine told me of this years ago and i'v done it about 10 times over the years and it works.it's like the egg that is layed and not let go cold,the new chick in it will hatch 2 days before any eggs that were let cool after laying

You're not having a laugh then. But I'm still a skeptic. :)

i use only hens to hatch so the natural way works best with this sort of thing.i'v spent years trying all sorts of things with fowl,some things work some things dont!i dont bother with books or google

i'm not saying every one should do this,i'm just giving a last chance for anyone that has a hen that has left the nest and it may be 4 days till you get another hen clocking.after 5 days dump eggs

Interesting Benny never heard of it before,it,ll go into the memory bank.

well, looks like 1 of 8 survived that cold spell, the first came out last friday and on sunday the hen walked, the other eggs were put under 2 other clockers but were quite cold and no chirp since, still nice that 1 made it.

Thanks for all the good information everyone.
