I've not been watching my girls daily because of a new baby, but yesterday I let them loose in the yard and my RIR is missing some feathers on her chest. There are a number of feathers strewn around the coop. This is the girls' second fall, they are about 16 months old. So far the other two (BR and BO) aren't showing any feather loss. Egg production has dropped significantly-- was getting pretty much 3 eggs/day over the summer and then about a month ago started getting 1, maybe 2. If this is molting, anything special I need to do? Especially if it gets chilly before feathers return? If it's not a molt, HELP!
