I moved my RIRs into their sweet new coop (about a month ago) and they started laying right away - 2 a day and on occasion 3. In the past week tho, one of them has stopped laying. I don't think she is egg bound, everything seems normal with her and I have not made any changes to their diet, etc. They have their laying mash, oyster shell and supplemental treats from me. They get free run of the backyard for a few hours in the afternoons. Lots of sunlight and room to run around. Any ideas as to what might be causing this? thanks!
