I've got an Ameraucana with a severe crossbeak - looks much like yours, and lurkys. She never did grow as big as her hatch mates; she's still quite small. But, she's probably 10 months old now, and she actually laid a few eggs for me last week! 3, to be exact. I'd never have thought they were from her, but I saw her lay them. And, they were good sized (1.75, 1.80, 1.80) for a bird that small. I felt badly for her! She hasn't laid since then, though. I don't expect that she'll ever be a good layer; in fact, I really wasn't expecting her to ever lay.
I do take her to a poultry vet once every 2 months for a break trim. I began that when she was a couple months old. I'd come home from work one day, and she was staggering around the run...I picked her up to examine her, and discovered she'd lost a LOT of weight. I felt so awful about it! I immediately began hand feeding her with a syrings, and within 2 days she seemed back to normal. That's when I took her to the vet and began the trimmings. Yep, I put $ into her (vet charges $18 a trim), but she's a sweetheart of a bird, so it's worth it, to me.
