Hi, I'm no stranger to roosters and for the most part can identify them before they crow but I am stumped. I have a hen who hatched out 10 chicks last spring, she is a Barred Rock mix and on the large side. There are 3 possible roosters, all 3 have different combs which is not unusual due to them being mixes, (now forgive my ignorance) all 3 have the slender, longish, feathers off to each side of their backs right in front of the tail, does this mean all 3 of them are roosters or can hens have them too? What are the chances that the 3 that look like her and that I really like turn out to be roosters. I tried to find an identification chart so I could tell you exactly which feathers I am talking about but failed. If I did not explain myself clearly let me know and I will try to get pictures tomorrow. Thank you in advance for some enlightenment.
