I wouldn't worry too much about seeing some odd behavior here and there, it's hard to know what exactly is going on inside. major internal injury causes a lot of tissue to bind together that doesn't normally stick together, this is often called adhesions and the worst of it is actual scar tissue. As Henry attempts to regain full range of motion he will be coming up against the restrictions and in some cases gradually tearing away the stuck tissue where it should not be connected. this can be a little painful but is generally a good thing. don't forget, he is doing stuff he hasn't done in a long time and it's going to take a while for him to "get back into his body" completely. I would think expanding on the jungle gym is very important, think back to early school days if you had a gymnastic teacher that set up a series of obstacles. one of the coolest one's I've seen is a large wheel on an axle that was tilted so that it became a treat mill of sorts, I added a link below to the video. there are lots of fun ideas, I'll post a few other video's below.
I would:
-raise his food and water just high enough that he has to stand up to eat and drink.
-make some snack/treat bottles that he can roll around and occasionally succeed at getting food from.
-hang high value treats to give him a challenge, maybe from something stretchy like a bungy cord. ideas: cabbage, squash, lettuce, kale, spinach
- give him exclusive access to a compost pile where he can practice scratching and using his foot more. some of what you are doing is trying to get him to forget that his foot is an issue and just keep trying to use it.
- add a hanging swing, using a 2"x4" with two holes in each end to tie the string in such a way as to form a triangle to stabilize it and see if he can get the hang of it. you could use a coat hanger to make triangles on either end and tie the string to that. if you look at a lot of kids swings you will see what I mean. https://www.google.com/search?q=swing+seat&tbm=isch&source=iu&ictx=1&fir=orpgcujQ7TDGKM%3A%2CIrC1ezvZGT-0LM%2C_&usg=__1I4K2HHmmXdPIgm9HhewLGY0SPM=&sa=X&ved=0ahUKEwiRiKaV39_XAhVC8mMKHQ45DjEQ9QEIwQIwCw#imgrc=orpgcujQ7TDGKM:
- add a perch for nighttime sleeping, made out of a 2"X4", it will offer a nice and wide platform.
- consider making a wheel treadmill:
some general ideas video:
all of this stuff can be offered up to your whole flock once he is "up and running".
