So my flock of chickens (with the exception of my bantams) are soooo skinny. I don't understand why. I am feeding waterfowl food (recently switched to turkey feed due to higher protein levels) and scratch. I also offer crushed granite. They are locked in a barn with an outside "run". They have access to food ALWAYS. Every time I pick one up, it disgusts me how skinny they are. Does anyone know what is going on??? I have dewormed with Valbazen but that doesn't seem to help. Any suggestions would be appreciated. Occasionally I have a death too and it's always a super skinny one.
