Man do I have some stubborn chickens. Trying to save money and get as close to breaking even as I can. My chickens are a bit over a year old. They are on Purina Layena pellets and producers pride scratch. Both gotten from TSC. They used to eat the Layena more than they do now. I have tried the Omega 3 layer feed too. They would waste some but I would go through a bag every 2-3 weeks for 6 chickens. Now they will hardly touch it. The scratch I used to use the Purina scratch. They stopped carrying it at TSC. Tried a local mill. They ate it but they were always acting starved. This was different behavior. Plus they wasted a lot. Then went to the producers pride. Still waste a lot. They pick out everything and leave a lot of the corn. It shouldnt be parasites. They act normal. Feather color good. No infestations that I see. I wormed them about a month ago. this has been going on for about three months. Pissing me off to see how much they are wasting.
