My guineas -- which are about 9 months old -- finally started laying for the first time. I noticed a nest on the floor of the coop but didn't see anything in it. They had hollowed out some alfalfa hay laying in the corner and today I finally see the eggs. There were 2 in there but then a little later I came back and one hen was sitting on the nest and another hen was sitting right next to her. ?? Later I found one more egg in the nest -- total of 3. She keeps coming back to the nest but doesn't sit on them all the time. She covers them with a little of the hay too. Do you think she will start setting? There was also one chicken egg in there today. Has anyone ever had a chicken take over a guineas hens eggs and hatch them??
