I am new to chickens, these are my first, I have a rooster and a hen, she is white and I had noticed that she was looking "dirty" and one of my youth kids had offered to help me clean the bird because she learned how to show chickens in 4h years ago, upon cleaning them she realized that they had mites, you are able to see only the shafts of some of my hens wing feathers, she showed me her skin and how it was white when she said that it should be transparent. So we went to a feed store and bought Care Free Enzymes Poultry Protector, because it was the only thing they had for poultry. So I am asking, is what my youth kid telling me right? What else should I know? Are the enzymes good enough to treat them, should I use it with something else? I have cleaned out the coop and am not sure what bedding to put back in. We live in the desert, I have heard that sand is good, but she said that mites live in the sand and I now have straw in there that I have sprayed down with the enzymes, is that what I should be using? Any advice would be greatly appreciated!! I just want my babies to get better! I guess this is all just a learning process, and I need some guidance! Thanks!
