I'm on the west coast as well -- southern ca -- & we just rode out a 101 degree heat wave that lasted several days. Your thread made me wonder about my girls too -- it seems like they all started going through their first molt a couple of months ago (on schedule -- they are about 18 months old). several lost feathers and now have new, healthy ones growing in, but i have one hen that has a completely bare bottom & seems to be taking forever to grow her feathers in! They all have slacked off a bit on their laying, but I'm still getting plenty of eggs. No pest problems that I can see, although I did find a cluster of nits a few weeks ago & removed them with coconut/oregano oil -- haven't ever seen a live lice on anybody & I did a lot of inspecting. They are happy, completely spoiled girls (and boys!) that free-range on about half an acre. Wondering if there's something else going on here? Do they just all molt at different paces? Should I inspect them more thoroughly? It's my first time observing my flock molt, so I'm not exactly sure what to expect...
