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...
