Hi everyone I'm a newbie and these are my lovely wee chooks that hatched end of March. Pics below including mumma hen who is very protective and the two possible dads Some look like they might be cockrels but its hard to tell, what age does it become more obvious?

2,5,and 6 definitely look like roosters. It depends greatly among different breeds. Like silkies take a year or more to figure it out.
