I had 5 now 4 RIR about 7 months old. They have been laying now for awhile. I was getting 3-5 eggs a day. I recently had a opossum kill and injured another about 2 weeks ago. I neutralized the problem and fixed the hole where it entered the run. The one injured hen is healing nicely. They are all back to normal but I only get 1 egg about every other day. Any reason for this or thoughts on how to fix?
