My chickens have lost feathers due to mite and lice infestations. They do not look terrible, but could use a boost. I saw this product http://www.nutrenaworld.com/products/poultry/naturewise-poultry/feather-fixer/ and noticed it is higher protein to help chickens recover quicker after molt. I have not been able to find it in my area. Would any higher protein food help? Can you feed adults a 24% chick starter or would there be ill results? Thanks so much!
