Ah yes I know what you mean now. They sure sound funny when they do that!They haven't quite figured out the crowing thing yet... there is a wheezy quality and abrupt finish. They sound like a squeaky dog toy equipped with an imitation rooster crow.
Here's another picture of Houdan 2 showing tiny comb and wattles. Such an odd bird - it definitely has those rooster saddle feathers but if it is a boy then the comb and wattle must be very very slow to catch up with the plumage - which is odd, because normally it's the big red comb that's the give away!
