So I have 4 ducks that are a little over one month old and they’re my first ducks ever. Everything was going great and they were happy and uninjured till last Sunday. On Sunday I noticed one of my ducks was bleeding on her wing so I got her inside and cleaned up and put some blue coat on her (which I now know not to do but it happens) she then got these like unopened exposed feathers but she wasn’t bleeding. Today I went out to check on all my ducks and I see something is wrong. Her feathers on her wings are exposed but not like opened yet. Half of her wing also seems to be falling off. She keeps trying to put her wings up but they keep dropping. She also keeps preening at her chest and picking at the wings. What should I do/whats going on?
