I purchased two 3 day old SS chicks on April 24th. They are supposed to be pullets. Looking at them now...I believe I have a boy and a girl. One is significantly bigger than the other, has a pronounced comb, brighter plumage and huge feet! The tail feathers are carried high. The other is smaller and lighter. Dainty feet. Has a smaller comb. Long tail feathers are carried horizontal. I have to figure out how to upload images as I am a new forum member. Thanks for your help!
