At what age can you sex. Ancona Araucana Barnevelder Barred Plymouth rock I've been told you can sex Ancona's at 3 weeks by red (male) or yellow (female) comb, is that correct/reliable? My rock didn't sit strongly as male or female on sight sexing so "rock" is still a mystery. When would it be worthwhile putting up pics of my chicks? They are about 10 or 11 days so I'm guessing I have a few weeks yet! I have six total and I'm hoping to start with a flock of around 4 so if I have mainly males I'd like to get some more asap so size is similar. I am only allowed six and no roosters so that's my upper limit. PS if anyone is around Sydney and after a rooster let me know as any will be free to a good home.
