Regarding chicks growing into roosters... I volunteer once a week outside Denver at a raptor rehab facility. Not to be gruesome, it is the cycle of life, but they are always looking for food for the birds of prey. The one I volunteer for is the Birds of Prey Foundation. There might be one near you. These birds are incredible - I get to be within feet of golden and bald eagles, hawks, falcons, osprey, kestrels...
The gals have been spending time outside with the warm weather (with the exception of the foot of snow we got two days ago which is now all gone!). I just put them in the dog crate and they dig and jump and cheep to their hearts' content. It's so adorable.
Also - I figured out why one was a runt! I had the breeds mixed up. The two larger ones are the americaunas and the little one - who is growing more slowly size and feather wise - is the gold laced wyandotte.
Put my top on a coat of paint and add some hardware cloth and will be done got 25 Americaunas will be here in two weeks thought I would get a head start get the coop built so when get there feathers I will be ready to move them out!
