My one EE flies linearly across the yard at about 4 feet, but she's pretty terrible at going straight up. She occasionally hangs out on the branch they have in the coop that's about 4 feet high but she has to really work up some jumping to get up there.
Mine have flown ten feet linearly, and onto the roof of my house. She only flew up there because we had friends over, and one of the little kids chased her around and scared her up there. We were afraid she wouldn't come down, but she jumped off by herself eventually.
