I recently had a chicken who fell ill so I had isolated her and nursed her back to health. I have been trying to reintroduce her to her former flock, and the other chickens are being especially vicious towards her. Today, two chickens cornered her while one hopped on her back and drew blood from her comb while pecking at her head. The oddest thing was that one of my roosters joined in and pecked her as well. Has anyone ever had a rooster join in when trying to restore pecking order??? I would like to note that I currently have two roosters in that same run (it is fairly large) and almost 30 hens. The rooster who pecked her is the less dominant rooster.
I once again removed her as I was afraid that they would kill her. I'm just curious as to whether the chickens sense something off with the her that I am not aware of, or if they're being especially aggressive because I haven't been allowing them to free range all over my yard for the last two weeks or so as they trash my new spring flower growth (thinking maybe they're just agitated and cranky). Any insight would be much appreciated! Thanks in advance!!
