i have a hen who started hatching a week ago. I candled the eggs last night, they all seemed to be developing perfectly fine. But I went to check on the hen this morning and she was off the eggs( I am aware that the hens do leave the nest once in a while) but the eggs were cold and buried in the shaving I left the hen with the eggs while I went to get a box to take the eggs When I arrived back she was sitting on the eggs again. I know she sat on the the eggs after I had candles them because I waited for her to. Should I take the eggs off of her and give her new one and risk her getting bored and leaving them ? Or will leave her with these ones? Could the chicks still hatch ???
