I bought my first chicks last weekend, 3 Crested Polish, and 10 supposed Cornish Rock pullets. First of all, they had them listed as egg birds, not meat, and I didn't know any better and brought them home. After finding out that they were meaties, and that I'd likely have to dispatch soon, I was ok with that, and ordered breeds that I wanted from McMurray. Now that they are feathering, most are starting to have brown and black wings. Help! What are my chicks?
