Two of the 'pullets' that I have seem to be developing pointed saddle feathers which I've always been led to believe was indicitive of roosters. I am a total newbie so it's very possible that I'm looking at the wrong feathers. The two chickens in questions are a White Rock and Silver Laced Wyandotte which I purchased when they were about 6 weeks old from a very well known breeder of heritage birds, so I'm assuming they would know what they were doing when I asked for pullets. Both chickens would be about 20 weeks old now. Would greatly appreciate if anyone could confirm the sex of both birds.
