Hi one of my hens has had a limp for about a week. I read today that Homepathic Hypericum seems to work well for some. Can anyone tell me a specific place where I can buy it in Houston? I've seen people in other posts say "health food store." But I need something more specific. I'm not even entirely sure what a health food store IS. Anyone who knows (a place to buy it, not the "health food store" part lol), please reply ASAP!
