I went out tonight to coupe my chickens and ducks. The ducks have started mating at four months old.! I found my big female roenan duck laying up against the pool ( 80 gallon cattle tub) in the shade, she hobbled and fell when I went to see what was the matter..Her foot looks crippled like, shes favoring it, won't put weight on it.. I brought her inside, put her in a large plastic tote box, with hay and food and water. she seems to be doing some better although she doesn't want to put a lot of weight on it..I filled the bath tub with about 4" of cool water, she was swimming around enjoying it, quacking away, shaking her tail in delight..she's very friendly and loves water. How do I tell if its broken.? Can she stay in the water for long amounts of time.? How long does it take something like that to heal.? should I keep her away from the other five ducks.? I would appreciate any help you can give.. Do they make duck vets.?
