My chicks are 4 weeks old and we've determined I have one rooster (it's crowed many times now) and a possible second rooster and even a third. At this point 3 of my 8 chicks are roosters but more than likely there's more. They're Americana mixes(EE). If I have to get more chicks how can I sex them for pullets at a day old? I'm really bummed that I won't be getting the number of hens I need and don't want to get extra roosters if possible. I'm willing to get sex links from tractor supply if I don't have enough hens but my mom says she wouldn't want to do that. Everywhere she's read said its bad. Help!
