I've got a few hens about 25 weeks old who since yesterday have started losing their 'real' feathers on their backs, and just have fuzz now, like what is usually on their butts. They act fine, but was wondering if this was some type of molt? They have just now started laying, so if this is a molt, why now, and will they stop laying? I believe there are a few that haven't even laid their first egg yet? Is this bad timing on my part as far as having chickens that start laying in the fall? If they are molting what do I need to do for them to keep them healthy? Could this be something else?
