Hi guys I'm new to this site and sexing chicks, we have 15 chicks that we rescued from a hatching program that would have ended up as dog food. What I need to find out is how I can sex them and find our roosters a new home, we have found a home for them but need to work out which are roosters and hens. They range between 6 weeks and 7&1/2 weeks of age. Any help would be great cheers
