Hi guys! I've been raising 2 wild ducklings for my local vet and have had them since about mid December 2016. It's now almost the end of February and they have all their adult feathers and can fly a little and are living outside (it's still summer where I live so pretty warm and not raining much). The problem is that they are not waterproof yet and I'm worried that the could fly off in the next week or two and still get soaking wet in water. Last year I raised 3 ducklings and they got waterproof on their own without a problem. I think thesee ducks are taking longer to get waterproof so is there something I could do to make get their oil glands working properly? Should I take them to the vet? Or is this normal? Any advice would be greatly appreciated!
