I have four 3-month-old pullets (Welsummer, Delaware and 2 EE) and one Jersey Giant cockerel, named Odin, also 3 months old. I also have 9 older hens around 9 months old. The problem is, Odin (who already out weights they pullets by a pound) has started all his rooster stuff and is now starting to grab the little ones on the back of the head and stepping on their backs. The girls freak out, scream and run. I've also caught my randy roo attempting courtship with a log, so I know his little hormones are in over drive. I really don't have the space for a private rooster pen or the supplies to build on. Questions are: should I move him in with the big girls? If not, will the little ones be OK with such a randy roo? If I do move him in with the big girls, will he be OK (being not so much smaller but younger then the others)? Will splitting the group of 3 month old chicks cause future problems? Will eating layer food be very bad for him, if I move him in with the big girls? I'm trying to down size my flock at the moment so the pecking order is about to get messed up anyways.
