I'm feeding them Purina laying feed, give grains daily and fresh veggies whenever I can get them from the market. I don't have any problems with rodents. I have suspected that my biggest problem is having too many birds housed in my coop. I need to sell at least half a dozen girls in addition to re homing this roo. Or get another coop set up, which is a possibility but I'd rather hold that back for whatever I will be doing next.
