I ordered 4 austrolorps from a hatchery, 15 total chicks. We got 17. One of the extras was a 5th austrolorp. From what I've read on here the "extras" are usually roosters. Now they are 23 days old. Of the 5 chicks one is a tad taller than the rest. It also started showing a comb about 5 days ago, where the other 4 had not. I did notice another one is starting to show a little bit of comb today. Also, the other 4 have tail feathers roughly 1 inch long, the "suspect" chick has almost no tail feathers. So, I have a slightly larger, little more comb, with not much tail feathers at 23 days old. Any opinions or experiences would be welcome.
