I have five chickens, 3 Dominiques and 2 Buff Cochins, about 18 months old. Right now, one of the Cochins is broody, and has been for at least a month. She stills lays, but is the only one. The others have not been laying for the past month. I also have several egg eaters. I think the brooder is one of them, but I have others. I took some advice from BYC and put eggs filled with mustard in 2 of the 3 boxes (the brooder is taking up the 3rd), trying to break them of their eating habit. Both the mustard eggs were eaten! Any suggestions? They seem healthy otherwise.
