I just bought 4 more chicks to replace the girls I just lost. I liked 2 birds in spite of the medical attention they needed. 1 of the girls is a EE and she has been picked on and the feathers have been pulled out of her back and near the tail feathers to a point they put the purple medicine on her to heal and protect her from the pecking. Then I have a Black Star with the same issues. My questions are, Will the feathers fill back in properly or do you think it was damaged and will not return? When this happen does it mean they are weak birds. Survival of the fittest per say? They are both very nervous birds compared to the others and hopefully with love patients and time they will settle down, you think? Any other issues that may follow because of this you think?
