I have a magpie duckling which I got for free with the run because its completely blind in its right eye and has a deformity on its right foot. Assuming something happened while developimg in the egg. Anyway, I have this baby in a cat carrier and am keeping it warm by a heating pad underneath the carrier. Its not too warm and not too cold. Always has fresh water and food. Its alone but has multitudes of attention from the kids and me. It can't quite walk right but can hobble to where it wants to get. But to get to the point I just noticed that it is breathing through its mouth. I can't see any obstructions in its nostrils and it isnt breathing hard its just breathing normal but through its mouth. Any suggestions to why or what i should do?
