A bit ago I went to check on my chicks and noticed a couple of them had dried poop on their butts. I watched them for a bit and did notice they had wetter stool than the other ones, so I took them inside to wash the dried gunk off of them. Dried them with a towel and then with a hair dryer on low (one of them almost fell asleep under the warm air) and then applied a little bit of organic coconut oil to the area. They're back out with the others now in the brooder, but I'm wondering what I can do now to try and prevent this from happening again? I saw some posts talking about yogurt and how it's good for helping digestion. Do I give them plain, unsweetened regular yogurt? Greek yogurt? Also, since they've been home a few days now, could it be the Vi-tal water they have in the brooder? Should I switch it to regular distilled water now?
