I'm new to this site and trying to find out if anyone has ever experienced perosis. I volunteer at an animal rescue (mostly horses) and we got in a duckling with leg issues. I'm not a vet and neither is anyone at the animal rescue so I'm trying to figure what is wrong with him and if anything can be done about it. I plan to take the duckling to the vet this week (on my own dime) and if it the vet says to put it down, that's what I plan to do, but if I'm told the duckling can live a good decent life, then I plan to adopt it. Can anyone offer any advice?
