I have 3 chicks, hatch on 3/21/12.So they are almost a month old. One is small no tail or comb to speak of, and is already turning a buff color, thus the name Goldie. The next one is a little bigger with a small tail and a comb starting to come and color. The last one is almost double the size of the smallest, has tail feathers and a lite red comb starting, it is also definitely the leader of the group and is very bossy. The local hatchery sexed the by the wing feathers. Do I have a roo and two pullets?
