Or girls do not seem to be laying as good this year as they did last year. I wondered If it could be the SS feed that we switched them to the end of last year. They are going on 2 years old now. But out of 25 hens, wouldn't expect more than 10-16 eggs a day? Also, they seem to be loosing too many feathers. They are Buff Orpingtons, but its just in the 80's here. It couldn't be the heat could it?
