I have 11 hens. 6 RIR and 5 Golden Comets. I had them all in one smaller coop and was getting 8 eggs a day. I separated them so they would have more room and now my golden comets haven't laid an egg in over a week and my RIRS are only laying 1 to 2 eggs per day. I've also noticed that 4 of my RIRS are loosing feathers on their breast area and wings. I have a rooster in the coop with the RIRSjust FYI. Any ideas as to why they've stopped? Also should I put them back together since they were laying better that way?
