Hi, I am lsc13151. I have 4 pet chickens. 2 are Rhode Island Reds and the other 2 are SexLink. One of my sexlink has a protrousion on her chest (crop area). She also has very pale crown and around her eyes. These are my pets that I raised from chicks. They are not laying eggs yet. I am really concerned about Dora. Some one mentioned ACV but I don't know what that is. I am afraid she is not doing well. Any help will be appreciated.
