So I'm pretty new to chicken ownership, I have a 2 month old black austerlorp (zilla), a 2 month old americauna (ester), a 2 month old black bantam (peeps), all of which I've had from day one, and a 4 month old partridge silkie bantam (lily). Theyve been fairly easy thus far, but I'm really concerned that one or more might turn out to be roosters (I got them from a local farmer and he didn't sex them). what are some early signs that they could be roosters? are roosters alright pets? and what age should they eat regular food...i have them on purina start and grow feed currently.
