I know the dogs (dad's) had worms, and I suspect that the chickens do too. Some of the chickens roost in the 'bunny room' of the barn. All the cages are covered, so no one gets pooed on, except for one side of a cage. Of course this is the side that the bunny's food is on, so the darned chickens poo in her feeder sometimes. I always clean it out, but well, Idk. The bunny is very skinny. If you run your hand down her back, you can feel every bone in her back. I don't think it is her teeth, I checked them and they don't seem too long. So worms is the only other thing I can think of. I have wazine wormer for the chickens, can that be used on the bunnies too? If so, what would the dosage be?
