Yes, I find the EEs and Ameraucanas both quite jittery and jumpy. I was debating about adding either a green egg-laying EE or another blue egg-laying Ameraucana in the future because I like the egg colors and the sweet temperament of the EEs/Ams -- but I just don't know if I should. Although my current girl is very sweet, a compatible flockmate, and non-combative, she is very noisy, takes long half-year breaks between laying cycles, and digs everywhere - she digs big holes scattering dirt everywhere with those huge toes of hers LOL. The other smaller breeds are less likely to dig other than in their dust-bath box. I keep my sweet Am around because she is easy to handle and pet and good with the other breeds even though she is the largest bird in the group. I love her but just don't know if I want another like her again. All my birds free-range the yard so I don't have to worry about pen issues but even then my klutzy Am accidentally knocked a Silkie off the nestbox ledge because she was moving in her jittery jumpy klutzy way and I had to take the injured Silkie to the vet. My small backyard setup may be too limited to handle this active breed but the EE/Ams are just so darn sweet it's hard not to want a couple of them around!
