I have a Buff orp that is laying eggs under my front steps.. She is letting other hens lay in her nest but none of them are staying on them.. They are laying the eggs and leaving.. Right now there are 8 eggs over a period of 5 days.. Is one of the hens going to ever lay on them or are the eggs going to go to waste?? Also I have a Whydotte laying a nest in a bush beside their chicken coop. There are 8 eggs in this nest also. 2 days ago there was a chicken snake trying to eat one of the eggs.. I STOPED that from happening so all the eggs are still there. The next day she was sitting on her eggs but only for 2 hours. She has not been back to her nest in two days.. Can any one help me with this I dont know what theyare doing or what this means.. Thank You!!
