I got my chicks from a neighbor who’s hen went rogue and laid some eggs outside of her property. We are not sure of the age gender or breed. She had 30+ hens and roosters so it’s hard to tell. Especially being born out of sight. I believed my chicks were 3 weeks until doing some google image searches. Please help me out. Deciding whether or not to get some more chicks, Incase some are roosters, to introduce before they are too old.
