Where did you get yours? If a hatchery, which one? Different hatcheries have different EE flocks that have different tendencies. If you can find someone that got EE’s from that same flock they might be able to give you some flock tendencies. If they came from a hatchery, they are almost certainly EE’s and not Ameraucana. Some hatcheries had the start of their colored egg laying flock before Ameraucana were even a recognized breed. There is a lot of history in colored egg layers and a lot of misinformation.
EE’s are not a breed. You cannot show an EE as an EE because there is no breed standard. That makes it hard to even define what an EE really is. Some people think they have to have the blue egg gene to be an EE but others think they just have to have that gene somewhere in their ancestry. Some hatchery EE’s will lay pink, brown, or white eggs instead of blue of green.
You can make an EE to look like anything. I know someone that has developed colored egg laying Naked Necks. In a few generations of breeding you could have Silkies laying colored eggs. I made mine to be full-sized black speckled and red speckled colored egg layers that often go broody. I’m sorry but just saying EE tells me nothing about appearance, what colored egg an EE will lay, cold-hardiness, foraging ability, personality, or anything else. While there is no universally agreed definition of what an EE is, they are almost always a mixed breed chicken. What they are mixed with has some effect what traits and tendencies they may have, but which traits the breeder is breeding for has an even bigger effect.
Don’t even start to think that 20 degrees Fahrenheit is even starting to get close to cold for chickens that have feathered out. With their down coat they are just starting to get comfortable. They won’t like a strong wind hitting them when it’s down below freezing, but your hot summers are your concern, not your pleasant winters. As long as you provide good ventilation, plenty of water, and shade, most chickens can handle your high temperatures fine. But the heat is where your danger comes from, not the cold.
I strongly suggest you look thorough that thread. Don’t be afraid to post on it either and ask any questions you have. There are some very knowledgeable people active on that thread and most are very nice people.
These are old photos but for fun I’ll show you some I used to have.
