I have a mixed flock of 10 regular sized chickens; 9 hens and 1 rooster, they are all about 3 months old. I hatched out 3 serama chicks in June, they all ended up being roosters. They are the friendliest little guys to people, love to run over to anyone and fly up to their shoulder to hang out - they are almost a nuisance they are so friendly. Unfortunately, they have started to be big bullies to the full size chickens! I was actually worried about the seramas getting picked on, not the other way around. These three little brats chase the hens all over the place, I even saw one latched on to a hens tail feathers as she ran across the yard with him in tow. Although the rooster stands up to wild turkeys that wander through; he doesn't do a thing about the little seramas. Anyone else have this problem? They are all free range during the day, the large chickens are locked in a coop at night and the seramas are still spending their nights in a very large brooder box in the garage - only because I was hoping they would eventually integrate into the rest of the flock and share their coop. Looks like I'm going to have to build another coop just for them. Not quite sure what to do; if they continue to act like bullies I may have to build a run to keep the bullies penned. Any ideas?
