Maybe they do. It could also just be that they have those genetics that were passed down through the EE line. But judging by the EE hens I can see in your pics, I can see how they kind of look like welsummers. That coloring is actually very typical of EE's, so they likely aren't first or second generation welsummer crosses. To my knowledge, hatchery EEs are made simply by crossing EE to EE.
First of all, a good rooster should never challenge you. Being friendly and/or cuddly towards him actually will sometimes make it so he's overly confident around you, which leads to attacking. Rooster brains are different from peoples', so they interpret the love differently. I do not have first-hand experience but there are many members who do and I highly recommend taking their advice. If your rooster does anything aggressive or challenging, my first recommendation would be the Stew Pot! You could rehome him, but I personally feel that passing problems on to other people is not how to solve the problem. If you don't want panic ensuing, you may just try to be calmer, slower and more predictable around the flock.
They were worth it though, since literally no one else supplies sexed bantams.Thanks for that! I guess in my mind I pictured those big hatcheries as only carrying purebred chickens and when they needed more Easter Eggers, they just took a "brown" rooster and put him I with some "blue" ladies (or vice versa) and let them go crazy. I have never really thought of Easter Eggers as a "proper" breed, although now that you explained that, I'm not sure why I didn't. Not proper as in standards, but proper as in a hatchery would keep an actual breeding stock of Easter Eggers that could be second generation (F2), F10, or F50...
Yeah, that's a common misconception. The whole origin of EEs, and the ameraucanas vs araucanas vs EE thing, can really throw people off. I think I have thought and studied this all hard enough to understand it, lol!
It all depends on the rooster. Some would totally thrash and abuse 35 hens, while others are perfectly content with just one. I would check the eggs, see if most are fertile, and if not you can try another rooster, just make sure he's gentle with the ladies.
His parents are probably also easter eggers, as most EE's are not the result of crossing two breeds, but the result of breeding EE together. So his parents, grandparents, and great-grandparents etc are likely all EE. Like I said, not all EEs are the result of blue egger x brown egger, but rather EE x EE as they actually came first, even before the modern blue egg breeds were created.
I hope you get that, it's complicated and I probably worded it badly...
Also, most easter eggers have small combs, regardless of gender. They are called pea combs.
Even professional sexers usually only get a 90% accuracy rate. So I'm glad you are able to keep him!
