sounds like it gordie
OP
that wrap does look much better. The horse feed isnt good for them though, they usually have alot of ingredients in them that are just as bad for angel wing as the high protein.
Just a basic 14% poultry feed is good, most any layer pellet or crumble is in that 14-15% range, just use that and you'll be fine.
Some birds, if they come from genetic lines that are sensitive to all this are just going to get it, others are tuffer and can eat 20%, so a lot of it can be from genetics, but the underlying cause is the protein levels and other nutritional things I mentioned.
Just head to your feed store and look for the lowest protein level poultry feed you can find and it should greatly help.
You can also mix in a lot of greens into their diets. Everything like that that you add, lowers the overall protien intake of the birds. Even corn will help, it's only 8% at tops, so the lower protein feeds you can mix into the diet will take away from their overall daily protein level intake and help correct the problem.
Once she's done growing and fully feathered, you can feed her anything you like. they wont get it as adults.
