This is a tough one! Penny, one of my buff Polish, is 23 weeks, hasn't crowed, has had just the slightest dark pink tinge around the beak for a few weeks now, but no actual wattles. His/her tail feathers are making me wonder a bit though. I also have a buff Polish about 6 weeks older than Penny who is definitely a pullet and has no pink or red in the wattle area at all, and then a white crested black Polish (95% sure pullet) that is the same age as Penny with red, developed wattles. Those other two have very wide, rounded tail feathers that just ever so slightly curve at the end. Penny's tail feathers are just a bit more narrow, and the top ones are a little longer and curve more. Honestly, the crest could probably go either way, and the saddle and hackle feathers don't look much different than my other Polish. I will post some pictures tomorrow. I know Polish take much longer to develop than other breeds, and I realize that development varies from individual to individual, but it seems like it should be more obvious by 23 weeks, no? Could anybody possibly post pictures of confirmed sex Polish, especially buff laced, around this age? Some tail pictures would be great, too!
