I have a small backyard free range flock of mixed breeds (buff brahma x, rir brahma x, speckled, americana, etc,). They will be a year old soon. They layed well all winter but I recently added a new rooster and the production has decreased as of late. The weather has been nice lately and all the birds seem in good health. So I'm wondering if hens take breaks from laying and so any insight as to why the decrease would be appreciated.
