Feather loss on chickens, moult or something else?

[5678]

After some thoughts on this and if I need to be concerned.

A few months ago my hens lost all feathers from their underneath, between the legs almost up to their rears. The hens are around 10 months old and were all bought from the same person at the same time.

I had a read up on it and had decided that with the longer nights, less daylight it was just natural moult and not anything to worry about.

Four of the six are well under way with regrowing the feathers, but two are still completely bald. There is no redness, they do not seem irritated by it and there is no sign of them scratching/pecking at the skin. Both are eating and drinking as normal and laying in full force.
The coop is cleaned regularly and dusted with a red mite barrier and this has always been the case. I've not changed chemicals or food at all.

So, as mentioned, any ideas what this may be?

I think they stop laying when in moult so probably not that, and the feathers should have grown back by now.

I'd suggest a health check at the vets and rule out any problems, and get them wormed at the same time

They didn't stop laying at all over winter. We saw less, but still a good 3 or 4 a day.

They are due to be wormed soon. I'll bring it forward a few weeks and give them another dose of flubenvet.

Taking a chicken to the vet will be fun!

They'll be ok, just use a normal pet carrier and pop a blanket over the top and it will keep them calm.

We see chickens, they cope well with it all. just make sure you find a vet that knows about them (one of our vets has an interest in chickens so sees and treats quite a few!)
