This is my entire flocks first breeding season ( abd mine too). I have 2 seperate little coops for my broody hens. One a partridge silkie hen that was sitting forever. She hatched 2 chicks succesfully. all the chicks after that seemed weak. So I brought them inside and put them in my brooder. I had a splash and a partridge chicks, both seemed ok for a few days and then died. I now have another splash chick inside right now. He seems ok for now. In my other coop I have my other partridge hen who hatched a buff chick. She is also in their with my cross hen who is doing all the sitting. She hatched a black chick this morning, I cleaned my run and checked in on them and I believe the partridge hen killed him. I am really discouraged with this. Could it be that its their first breeding season?
