Hi! I just joined I have 2 black copper maran chicks and one splash blue isbar at 3 weeks. All of their combs are forming as well as tail feathers (feathers came in for all fairly early.) Anyway, i was looking at sites about sexing and came across the site the chicken chick who ive heard is really a good source of info. However i cannot directly ask her, so any feedback would be great. I am attaching the 2 pics of the marans as well as the isbar. I have no clue with the isbar as I dont have anything to compare him/her to. But the chicken chick did post a collage pic where she sexed the black copper marans at the same exact age of my marans and even still, im having trouble determining. Please help The collage is from the chicken chicks site. Thanks!
