Hi! I'm brand new to this forum and to backyard hens, so please let me know if I posted this in the wrong place. I have three "hens" right now, two Barred Rocks and one Delaware. My concern is because my town is run by some real small minded, totalitarian dictators who equivocate hens to demonic forces from hell (yeah sadly NOT joking or exaggerating on that) I am only allowed to legally have 1.5 hens (and hens only) in my backyard. Not sure how they think I was gonna pull off the .5 of a hen but I figured, their stupid rules-- they can round up. Long story short, I'm at least one hen over and now I am concerned the Delaware is a roo. If he crows I'm done for, but it seems like the only advice I can get as for telling if he is a roo or not is "wait till he crows".
Anyone know any visual clues that might tell me he's a roo before he crows?
Pretty much he's older, but skinnier than the other two. He does not "strut" noticibly yet and for some odd reason, despite being 12 weeks, all of their combs and waddles are just now starting to pink up and sprout. The one thing I do notice is he has really long spear shaped neck feathers that he fluffs up a LOT and is slightly more aggressive than the other two who are Barred Rocks. Most the Delaware roos I see online have longer neck feathers than the hens. Are these feathers a good indication of his gender? Any info would be really helpful!
Thanks!
