How much alfalfa are they getting? Is Marco timid? If so, how timid? Given the history you've outlined, the only thing I can think of is complications due to the possible polio, or he is being pushed away from the feeder and can't eat.
If he were mine, I would 1) get him in his own pen or out of there asap! I know you're trying and I'm not suggesting in any way that you're not. Unfortunately, **** happens.They are fed together, I believe three flakes twice a day, that's why I supplement as much as I can![]()
I would stick with the grass until he gets some weight on him, then transition to alfalfa if you want to. It's much easier to avoid health problems than it is to treat them - especially where you are not able to easily treat him should the alfalfa cause diarrhea.Should I just get alphalfa? Or grass hay?
