I have an EE cross pullet who hatched with feet much like your little guy's.  The toes were crooked and contracted, her legs were weak and contracted, and she couldn't stand up.  It wasn't spraddle leg but I did try the bandaid hobble for awhile; it just made her flop onto her side.  She could sort of get around on her hocks but fell over a lot and consequently didn't move around much.  Every day I debated whether to cull this messed-up little chick but she was keen and never complained so I kept helping her to the food and water many times a day.  I also did some movement therapy by gently straightening and moving her legs; perhaps I should have done more of that.  Eventually she was able to stand up a little and scootch around.  I splinted her feet which helped a lot for awhile - they looked almost normal for a couple of weeks - but then her toes curled with a vengeance.  Today she's 18 weeks old, with messed up feet and oddly stiff legs.  Up until about three weeks ago I had to help her onto the roost at night (she can't jump well so had a hard time getting up) and take her down in the morning, but now she manages just fine on her own.  She marches around and can even run (with a funny stifflegged skipping sort of stride).  She's incredibly friendly and tame and has become my favorite chicken!
