Hi everyone, I ordered my first group of baby chicks from McMurray late last year, and they are scheduled to arrive soon!! I am absolutely thrilled! My main question at this point is, how do I tell the chicks apart? I ordered White Leghorn, Black Star, Silver-laced Polish, Buff-laced Polish, and Ameracauna chicks. Because of the minimum order, I ordered more chicks than I want to end up with as layers. If I wanted to sell or give away the extra chicks to friends, how will I know which ones are which? Thanks so much for any advice!
