I was doing some research on cross beak and found someone talking about cell salts/BioPlasma and it looks like a miracle product for all sorts of things. It is not available at my local GNC so it would have to be ordered and before I buy it I would love to hear from someone if I should get it or not. If you used it and the cross beak situation improved. I have a 12 week old silkie rooster who developed cross beak about 5 weeks ago and it's not that bad and thought maybe it might straighten out. The original post said it was from a lack of nutrients or something and could be reversed.
