I have a mixed flock or 3 buffs (one is a rooster - got 6 chicks from TSC and 4 turned out to be roosters so we had three rooster dinners), 2 olive eggers, and 2 splash marans. The olive eggers and marans came from a breeder and we got them when they were about 8 weeks. The buffs are about a year old and the rest are maybe 4 months younger. The pecking order is rooster, 1st oliver egger (acts like a body guard for the rooster), buffs, 2nd oliver egger, and the splash marans at the end. The two splash marans are smaller and spend most of their time together in the corner of the run or just keeping out of the way - mean to build them somewhere to hide. The rest will flock together and get on quite well. Our rooster is very rough and one buff and the splash marans now have caps as they are bare backed. The others are heading that way as well. We had been getting 4/5 eggs a day and that has not gone to 1/2 eggs a day. We did move them to a new run with more space (8'x24'), but the coop (4'x4' - 3 egg boxes) is the same. They also have a larger run that they go in when we are at home. They have been in this new place for about 2 months. I know there could be alot of reasons for the egg production drop. But I am wondering if the reason for the egg production drop is due to stress from the rooster? We did have a bit of a lice out brake when they were in their old run, but that did not effect the egg production. They were on ~2lbs of feed a day and I have gone to free access and they still eat about the same amount. I do give them access to oyster shell and old egg shells as well as grit.
