I am planning to hatch some eggs in the near future, and I have a couple of questions about roosters, which I really can't keep once they start crowing. 1) I understand it is hard to tell a rooster from a hen until they are almost full grown. Will it be easy to tell at that point? About how long until I can tell which ones are roosters? 2) How hard is it to get rid of roosters? If I just put a "free" ad in Craigslist or freecycle, will it be easy to get rid of them? Thanks!
