oh, and speaking of roosters... do you know what they do with male chicks?
They hatch, and the vast majority of them are immediately killed... according to some people (I can't say I know for sure this), they're either put in dumpsters and just let suffocate, or they're ground up alive into animal feed or fertilizer, etc.
Keep in mind that one half of all eggs are male.
Why do they kill them? because one, roosters are aggressive, and two, roosters don't lay eggs. The only reason they let a very small percentage of those born live is to keep making hens.
and speaking of aggressiveness, since chickens are so crowded and stuff, they also cut (half of) their beaks off (I think this is for meat chickens). They do this because crowded conditions make them stab each other with their beaks, which is of course bad for business.
And that's supposed to hurt... also, I think they use a hot thing to cut their beaks off, so that they don't bleed too much... does anyone know more about beaks? hmm... I'll make a new thread.
