I wanted some pretty yard decorations so hatched some eggs out of my Partridge Brahma and Blue Buff Splash Cochin hen. Got quite the rainbow too! Also one Bramha x EE that is freaky large, I'm guessing that thing is a rooster? The two largest are 12 week olds ( 2 - blue and 1 - buff partridge maybe?) The other large thing with the blue neck and red feathers is that 8 week old EE x Brahma. Never had anything grow this fast, it hatched at the same time as the smaller chicks. So, guess on gender (or color)? I am suspecting that I have mostly roos in the younger group.
