Well, Rog, your inbox is full, so here's the answer, LOL. That does sound like alot of Splashes in a small group, but it may just be the luck of the draw, genetically. I rarely get a splash, maybe one from each hatch, if I'm lucky.
In this breed the cockerels feather out VERY slowly on their backs and under their wings. Suede was almost completely bald for two weeks on his back, poor thing. Also, the sides of their necks are sort of bare sometimes. The girls feather out much more evenly. And the boys do appear more bobtailed. So yep, you're right. The combs on the Orps are not usually large like BRs, so sometimes it's hard to tell by those, but the boys get wattles quicker than the girls. Hope this helps.
