I’m attaching a picture of what I’m taking about.... I have 3 Dominickers I got in November at 7 months old. They came to me looking like this, only one of them has grown feathers and a tail on her butt. The other two remain with red, naked, yucky looking butts. Does anyone know if this is behavioral plucking and pecking or if they have parasites? They are voiding and eating and laying eggs normally and do not seem bothered by this at all. Any help is appreciated! Thank you!
