Hi, I have a chick who's dad is a Buff Orpington and who's mom is a Barred Rock. We were told that it is a sexed linked cross, males have a dot on the back of the head, females don't. Well turns out we had 4 chicks, 2 were black with a whitish belly and chin and 2 darkbrown with a lightbrown belly and chin and white spot on their throat. I kept one of the brown ones. I was convinced it was a girl until just recently. It's 8 weeks old now and I found it has always made roosters sounds, even when it was a few days old. Not crowing, but the clucking sound they make when they've found a treat (or food dish, in this case) and I today heard the sound that roosters make when they see something potentially dangerous, like a screechy growl kind of. Also, I find that the wattles are fairly large for an 8 week old pullet. There is no redness though. Also the neck feathers seem pretty shiny, but I think it's a little early to tell. Can someone guarantee me that this cross is a sex link? Is this a girl or boy? The following picture is the only one I have, it was taken at 3 days old (note white spot on throat) . More pics will come tomorow.
