Different breeds will be different, even down to each individual bird.

I was gifted an EE as she walked up in the guys drive, her wings were both severely clipped. I accepted her and soon found she could jump at least 8 feet straight up.
As to lift, how much lift do you get flapping your arms, thats all she would have got. Poor girl!
I did find the issue, she had feathers covering her eyes, everything that moved was a predator. Once these feathers were clipped I sat her down, her head held high. She spots the rooster she had been running for her very life from, ran straight to him and squatted! Was he proud boy then,,,
