Broken Beak and Broken Off upper Mandible

[carrotcritters4h]

I have two valley hens who have i beleve hit their beaks on the size of the coop and one had craked her uper mandible and the other has copeletly lost it. I was wondering if there was anything that i could do to help them. They seem to still be able to eat and drink ok but it is hard for them since their nostrils are all scabbed over. Any thoughts are appreciated. thanks
