Pros: Friendly, good egg layer, curious
My two EEs are super-friendly. They really don't care if you pick them up. They are pretty good egg-layers--mine stopped laying early-November but started back up again around the holidays, each lays 4-5 eggs/wk. Great bird.
My EEs are also incredibly curious/maybe even a little naughty. My coop is built into my shed, so it has a door connecting the shed to the coop so that I can go into the coop and whatnot. So one of my EEs hops out of the coop when I open the door to check their feed level and starts running around in the shed. (I'm chasing her around and trying to get her back into the coop.) Eventually I can get her close to the coop door, so I open it and my other EE tries to hop out. I have to shut the door in her face so that she also won't get out and then that scares the first EE who's still running around in the shed . . .
Eventually I got her back in the coop, but it took a while. So if you're not okay with chasing around chickens trying to get them back in their coop, then don't get EEs. Otherwise, EEs are awesome.
