Just read through all of this thread. It makes me feel so sorry for all the poor little birdies. lol
I have a silkie hen named Muppet that has a minorly crooked beak.
Currently have a couple special ducks from this past season's hatch...
One blue Swedish mix hen that got the end of her beak pecked raw by some by some baby guineas when she was a baby. As she grew and it healed up, the pecked area kind of shriveled up, for lack of better words, so her top bill doesn't fully cover the bottom by about a half inch or so maybe. There's one little peak that sticks out in the middle, and the rest kind of curls in from the sides to make the shortened bill. (Hard to describe, that description probably makes no sense. LOL) She eats just fine though, so it's just a cosmetic defect for her.
The other little black Swedish mix drake is pretty much a miracle that he survived.... When he was big enough to start living outdoors, a goose, I believe, beat him up badly. Had fluff pulled out bald in spots, one side of his head/face particularly. I think one leg/foot was kind of swelled and messed up. And his bill was "broken." His upper bill was swelled up. His face looked awful. And he couldn't stand, or sit, upright without falling over.
He maintained his appetite and would eat and drink though, but I'd have to try to set him up so he could eat and drink. Sometimes I'd hold him in place while he ate and drank some. I didn't have much hope for him, but I kept flipping the little guy back over and setting him next to food and water.
And lo and behold, the little booger pulled through. Got better. Got up and started walking. Took quite a while to recuperate, but he did.
His growth was somewhat stunted from this process, so it took him longer to get feathered out and gain size and everything.
From his beak being broken, it has grown to be crooked and funky looking. But he does alright, all things considered. lol
