i posted a week or so ago, but chicks have grown quite a bit. i have three 4wk old mille fleur d’uccles and 6.5wk old bantam Mottled Cochins. Can’t seem to figure out sex on some of them. one of d’uccles (on left) is definitely a roo, and one of cochins (on left) is probably a roo too. what about the others?
