hmmmm. I guess I am not that diligent with my crew. they get DE in their coop and their dust baths. they get blue seal layer pellets and whole corn. they also get all the kitchen scraps I can give them......from left over cooked meat to left over waffles. I have only 10 layers and get 7 to 9 eggs daily. the weather is turning cold so I expect the production to go down some. my crew consists of rir, Sussex and leghorn mixes and a very nice rooster. do you have a rooster on premises???? they might feel safer with a couple around.
