I have no idea if this is even the right place to post this, but I was a bit stumped so here it is! I was given two pretty blue cochins in September, when they were about two months old. I'm pretty sure one is laying, since the other birds in the pen are all older and have been producing regular size eggs for some time now. The other one is developing slightly larger combs and wattles and I'm suspecting she is a he. Last night I found this sexually ambiguous cochin in one of the nest boxes, when usually all the chickens roost together on the bars provided for that. There was a runny poo stuck in the down feathers on the backside, and I lifted the feathers to see if there was any injury and got a very good view of the vent. When it flexed (as I'm told happens all the time with chickens for no apparent reason) I could see inside the vent and there were two small bumps on the lower half of the circle of the vent. Nothing looked red or swollen or injured, so I'm assuming that's the chickens normal anatomy. Does this sound like a hen, or is this one a roo? Or can a person even tell by looking there? thanks!
