OK, I'm pretty sure my chickens are molting.... (I'm new to this). Their feathers seem to fall off practically over night... They look atrocious, they are eating and drinking barely at all... they are not laying eggs... and they are skinny. Other than THAT they seem perfectly happy, scratching around pecking at this and that. They look pitiful!! Also... one in particular, who doesnt look that pitiful, lays in the nest... but only at night she's up and about all day. Since they don't have any eggs in there, I've been letting her stay there, since she comes out all day long. I am thinking she is NOT brooding... But I find it odd that she does this. Any thoughts?
