so we have two rouen ducks a little over a month old and one injured his leg and can't put weight on it. we're planning to bring him to the vet, but there's no emergency vet nearby and none of the vets in town can fit him in until sometime next week. but since he's eating, drinking, preening, and pooping we're not too worried at this point. we're thinking of making him a duck wheelchair (hopefully he'll only need it temporarily, either with the issue only being something that will heal up or he'll learn to balance on one leg) and we were wondering what would be good flooring in the pen we're going to keep them in that would best allow him to use his wheelchair in it. right now there's thick grass in the bottom and I'm not sure how well that'll work with it.
