This morning my midget white tom is very unsteady on his feet and at times is falling down. He then sits there on the ground. If the hens come by, he attempts to spread is feathers (strut from a sitting position is what it looks like). What to do?? We feed a custom mix w/ 24% protein. He's our only tom. Two hens. They are currently housed with a few runner ducks if that makes any difference.
