I have 2 hatchery-raised birds (bought them around 9/10 months old). Since they never had access to hard ground, the claws on their toes are really thick, long & deformed. Any suggestions on clipping their claws? I've got dog toe-nail clippers, would they work? These girls don't like to be held, so what would be the best way to hold them & clip? I thought that if I let them roam loose, they'd eventually work down to normal, but that hasn't worked.
