I have 3 hens in my little flock - one (GLW) molted recently and the other 2 have never molted. All are about 18 months old and we live in FL where we're having a mild winter Two of my hens, a BA and a RIR, have bald necks. We have no rooster and they seem otherwise healthy and happy. Of course I could only get blurry pics, but you can see their bald necks here. Is it the start of them molting or do I have my first ever mite problem? I know if it's mites I'm supposed to get sevin dust and dust them and their roost, right?? I guess I don't want to buy it and dust them if that's not the issue. I've peeked around their feathers and I don't see anything, but I know little mites and such are hard to see.... Thoughts? Looking back at photos, they've looked like this for about a month. WWYD?? THANKS ALL!!!!!!
