My 2 yr old BO lost many feathers to a rough rooster about 5 mos ago. I have done everything to help her grow back her feathers - extra protein, special avia nutrients. She's got a bare back, head, and edge of her wings. The new roo is quite easy going and is not being rough. Every few days I give her wet cat food to help out too. I've kept treats to a minimum. Any other ideas I'm concerned as the weather is getting cooler now.
