That is too bad, and messy!
I would like to hatch eggs under one of my hens as well- when the time comes...
"bargain" is selling lavender project eggs right now- reasonable price. I plan to get
them from her (nice farm, seem very honest), She has many others (Sussex, Delawares).
Don't give up- try again.
Thanks and im not going to give up, i had this welsummer and she had 26 eggs under her (far to many) non hatched the year after that she went broody and she had 8 eggs one was just 8 off hatching and another hen stood on it and cracked it
and this march i found her lieng dead on her back in the feild
Just make sure you don't give your broody hens too many eggs - You can give them up to as many as they can cover.
A mother hen, when turning her eggs, shifts them around. So if say there is no room for two or three eggs and they sit out from under her, eventually they will be moved back under her and another set of eggs will take their place, chilling them all slowly.
So to maximize your success, less might actually be more!
