Ok, so i'm new to chicken ownership. I just bought a Marans pullet, about 10-11 weeks old. I have 3 Ameraucanas the same age, from the same breeder. The new Marans pullet has no tail. He wasn't sure if she plucked it out herself, or if the other pullets she was with did the damage. Her skin looks fine and I'm hoping her tail grows in, but is there anything I need to do in the meantime? I'm keeping her separated from the other pullets, they were pecking the area. Will she be ok alone? Any advise would be helpful. Thanks!
