Hi guys, my silkies were born 5/14, so they're almost 4 weeks old. I have 8 straight run. Here's my question: exactly 4 have big round powder puff tails and 4 have pointy feather tails (more like my other chickens) The four with the feather tails have wide combs, while the 4 with the cotton ball tails have narrow combs. I keep hearing that sexing silkies is next to impossible. Are these things just coincidental??? Thanks! also the feather tailed chicks are noticeably heavier too.
