A school has 12 Isa Brown chicks that they hatched and are trying to get rid of. Is there a way to tell their sex when they are a week or two old? Now is not a good time of the year to get chicks but they're free and if I knew they were hens I think it would be worth the effort. I'd rather not have chickens taking up space all winter in my heated garage to find out that they are roosters.
