Hello, I purchased a package of Recover 911 for my chickens and this website is on the box.I’m fairly new to chickens. My oldest 4 I have had for over a year and a half, I had to rehome my rooster as he was 2 much for my ladies. I am still dealing with 2 that have not grown their feathers back, I thought the recovery 911 would help them but I have a couple questions. First, can I give it to all my birds? They range from over a year and a half to 3 months old. Second, do I only give them water with the recovery in it or do I also continue to provide clean fresh water so they have the choice?
