So I've added new chickens to my flock twice before; however, this is the first time that the newbies are outnumbered. First time I added a chicken, it was one on one. Second time, it was two on two. Now I have four and am adding two. My existing flock has an EE hen as old as 9 months and some pullets that are 5 months. The new pullets (about 4 months old) I'm adding have been in their own little "coop"/doghouse with attached run for the past month. For the past couple of weeks I have let the little ones out to range with the bigger ones. The bigger ones mostly leave them alone, except for the occasional chasing. But the little ones have enough room to get away unscathed. As of last night, I put the new ones on the roost with the other chickens and they went in well with just minor grumblings from the peanut gallery. Today they have spent most their day hiding in the nesting boxes. The couple of times they go out into the run they end up getting chased, and pecked. There's not been any blood, but I have seen some feathers get pulled out. So my thing is, I hate watching these feathers getting pulled and the babies hollering. Sometimes my head hen will chase one and peck several times, usually getting contact with some (occasional) feathers. At one point I felt like she wasn't letting off enough, especially with the other 3 chasing so I took her out and separated her for now. Should I have just left her in and plucking feathers is okay (for the time being)? How do I tell when the pecking and chasing is excessive? Only when there's blood? And was I too rash and protective of the little ones for taking out the head hen? I'm still learning so I would appreciate any and all input!! It's so hard to sit by and watch it sometimes!
