We bought 2 chicks that we were told were Golden Sex-link pullets. One is now crowing, so I guess it's a cockerel, but that doesn't necessarily mean they both are, right? I'm thinking that a Golden Comet cockerel was put in by mistake? We have other chickens but we're pretty sure we only hear one crowing. The larger one definately has spurs growing but the smaller one does not. They are both bought at the same time, about 15 weeks ago and from the very beginning two were always chest butting, this large one here, and a RIR, which also turned out to be a roo. Now these too will kind of stand close and eyeball each other. I really hate to get rid of a hen by mistake, but we have to get rid of roosters in this neighborhood.
