I'm new to raising chickens, and am having trouble figuring out if one of my ladies, Louise, is actually a roo. I've started calling her Lou in case we need to make a gender switch. S/he has a more developed, and more red comb than my other lav orpington, but other than that doesn't seem to show other roo qualities. S/he just recently started making a new noise that the other chickens don't make. I can't really explain it but my first thought was a terrible attempt at crowing. However, after looking at some other posts, I'm wondering if that noise is actually an early attempt at an egg laying song. S/he also doesn't seem to have pointy saddle feathers, but they do seem a little more messy looking than my other lav orp, as if s/he isn't preening as well or something. I've included some photos for reference. Thanks in advance for your help!
