Ive hatched 13 eggs now in ine weeks one of my chick got a beutiful tail like a hen but in two weeks the chicks comb is also getting bigger ive heard females get their tail firsy and male get their comb first

Fast feathering can be a sign that a chick is a female. But, it is far from being 100% accurate. A fast growing comb is a much more reliable sign that a chick is a rooster.

It also depends,well sometimes,the light and darker shades of red.
Sickle feathers,saddle feathers, are the real truth.

They don't all necessarily,comb first,feathers first.
Pullets grow wing feathers first,a cockeral,well,it could have a number of things indicating male,or female.
