Kids and I were watching "How it's made" tonight and the show was about hatching eggs and what happens after a chick hatches. Poor things being tossed all about. They showed these ladies picking up chicks and checking the wing feathers. If the feathers were all the same length the chick was a hen and if the feathers alternated long short long short it was a roo. Anyone ever heard of this? BTW watching How It's Made got me started with chickens in the first place watch the show about the poultry houses and the horrible environment!
