I believe my Rhoade Island Red hen has been evicted from my flock, they attack her when she is near, and is chased off, they won`t even let her in the coop, we let her in several times and they chased her back out. I first noticed this about 5-7 days ago, and it has escalated terrifyingly since then. She now has a bald spot on the back of her head, though it is hard to see, it was bleeding and has now scabbed and might be pushing new feathers, there are rips on her comb that have scabbed. She can`t go anywhere near the flock, they attack her, so she is now sleeping in our barn (Which is not the best place). It is not just the roosters that are attacking her, but the hens also. And they will all chase her away from the food. Any ideas on what`s going on? Is there a way to stop this? Thanks in advance!
