Large Fowl Modern Games

Hey! I might get some modern games in the spring, but I need some more information about them. Here is some information:

1. I am going to be showing these birds in 4-H, not breeding or big-time showing or anything.
2. My 4-H club is going to be ordering in one big chick order in the spring from Murray McMurray hatchery. The hatchery has Black breasted Red Modern Games, and if I choose this breed, I will be ordering 3 females.
3. Apparently, standard Modern Games are not very popular in the US at the moment, and I can't find much information on the breed.

Here are my questions:

1. How big are they? I know they weigh about 4 - 4 1/2 lbs (females), but how tall are they? Can anyone provide a picture comparing them to an object so I can see the size? I want to know the height, and can they easily bend down and pass through a smaller opening (like the coop door opening)?
2. Are they friendly and easy to tame? I have heard they are from several reviews on another website.
3. Are they flighty?

Thanks! I hope you can help! If you need any more information, let me know!
