My polish hen went broody on June 30th. I do not have a rooster so I put 4 fertile eggs from a friend under my polish. I marked them and all was going great until today when I got home from work i checked on my polish. All 4 of the marked eggs were gone (except for half of a shell) and my polish was sitting on the 3 eggs layed today by my other girls.I check for snakes frequently. My questions... do squirreles take eggs? could my other chickens have eaten them? What do I do with my broody polish now that she has no fertile eggs?What did I do wrong? I'm so sad.
