I buy 17 % laying pellets & want to up the protein. What should I get to mixs with the laying pellets. The pullets are laying alot of eggs consistantly. 8 eggs a day average from 10 pullets. I'm thinking I'd like to add about 3 % more protein to their diet this would boost the protein to 20 %. I'm having problems with them pecking each others feathers out. Any suggestions before I go. Also, could you give the ratio of how to mixs. The laying pellets come in 50 lb sacks. Thanks in advance.
