ITCHY 2 DAY OLD CHICKS!! They arrived yesterday from Meyer Hatchery. Within a few hours in the brooder, all 3 started itching like crazy. I thoroughly cleaned the crate they are in. It's lined with an absorbant pad, a nice later of freshly opened pine shavings and then 2 layers of paper towels. I'm very perplexed. aside from the itching, they are eating, drinking, pooping and sleeping.
