I have 7 Jersey Giant hens, 3 bantam hens and 1 bantam rooster (Artie) who takes care of them all (or is at least trying). Joanie, the mixed cochin hen, went broody so I let her keep 3 eggs to see if they would hatch, although I had no idea whose eggs they were. I marked them with the date we started. Well, the biggest JG hen started crowding into the next box with Joanie, sometimes during the day and sometimes at night instead of sleeping up on the roost with the others. One by one over the last two weeks I found those eggs pecked open. The first 2 were just plain eggs but the one I found yesterday had a baby chick inside, so it may have been hers. Artie mounts all of them but I have no idea if he succeeds with the big girls. Should I have moved Joanie to another coop while she was nesting? Should I have moved the mean girl to the other coop? Was this a kind of bullying? The JG's lay eggs all over the sand in the coop, not in the next boxes, and I've never found other eggs broken open. I felt bad for poor Joanie.
