My last hatch is 8 weeks old now. A good share of them are no brainers, (except the couple silkie mixes and polish). The boys have big ole pink crowns and wattles. The two for certain girls have tiny yellow crowns. But this one is in between. (All of mine are mixes.) This one is apparently an ee as he is sporting little muffs. His comb is quite a bit bigger than the girls but half the size and not as round as the boys. It's also a nice pink. But his wattles are almost non existent. I realize this could be due to different mixes. My sister is going to be taking my roos and I want to be more certain before I send him off and plan out my next game plan. (I'm just starting my flock and think I'm taking quite a hit in the girl vs boy ratio....lol) Here's my problem child: The other boys pretty much follow this trouble makers traits where crowns and wattles are concerned: Also, at what age can someone who knows what they are looking for determine sexes for silkies and polish?
