This year will be my first year raising chickens. Locally there are only two breeds I can choose from when getting chicks, grazers and cornish. I am going with the cornish. Am hoping to raise 50 or so birds. http://www.bergshatchery.com/cornish.shtml - that is the site I'm ordering from. Anyways my question is, which are raised for meat? the Hens or the Roosters? I'm assuming hens? what if i just ordered 50 mixed?
