Can a chicken molt when it is 3 years old? What causes this? Anything I should do for her? Her skin looks pink and seems like there are pins for feathers growning back in... her belly skin is kinda flaky though. Could this be lice?? what does chicken lice look like ? How do I tell if she has lice? How often do you need to dust chickens for mites? Is there something to dust them for lice?
