So I started with a flock of 6 mixed breed chickens, then last October a neighbor's lab had a chicken dinner, and I had a hen go broody so we got her three chicks to raise. Here we are in the end of Jan. with 8 chickens (two of the chicks may be roo's- but that's a different post on a different board). Prior to this past fall we really had a great group of chickens- none had any major pecking order issues. We noticed there were two that seemed to share the top spot, and two that shared the bottom but there never seemed to be one set in stone. With these new young chicks added it seems to have thrown things off. I'm not sure if it's stress from the cold Utah weather, or if it's the fact that two of these newbies may be roos, or what but my sweetest chicken of the bunch (a buff orp) is now pecking/picking on the smallest of the three new chickens. The other two new chickens are HUGE and they even run away from her! She used to be super kind and loving even towards my kids/toddlers! Should I wait until there's a problem (missing feathers) and just watch or is there something I should be doing? There is a fence around an old wood shed (where the mama hen raised the chicks) and their original coop/run so there's a lot of space for them to get away from each other, and I like the idea of letting nature run it's course but I'm concerned about this hen pecking on the other ones because it's so unlike her. Thoughts??
