I've been thinking for almost a week now that mine are going through a "mini molt". I was getting 8-10 eggs a day from 11 girls, and all of a sudden that has dropped to 4-6 a day as of a week ago. Mine are 8 months old and I remember reading that they might go through a mini molt at around 8 months. Today I noticed a very large number of loose feathers from my 3 dominiques in the run (much more noticable than at any other time), so I'm starting to think they are molting. I also haven't seen my 2 black australorps in the nest boxes in over a week (but no black feathers; just the dominique feathers in the run). I wouldn't call it "cold" here, but this whole week the weather has been unusually mild compared to prior weeks and compared to the average temps for August in GA.
