Looking at her I’d say her beak is because of her facial deformity. I don’t think you can really “fix” that. You just have to make sure she’s got access to food she can scoop with her bottom jaw. I’ve heard some people try to correct it by gently putting traction on the malpositioned jaw but I don’t know how much that actually does or if it would harm her, especially in a case like hers with more going on. I definitely wouldn’t be putting tape anywhere near her face...
otherwise she looks pretty good from the pictures. Is she trying to walk at all? At least she’s got her legs under her!
