I have a Canary chick with a splayed leg.

Right now I have the chick in a very small cup to help hold it in correct postion. I am also hand feeding it. because the hen squishes it so tight under her the chick can not pull its leg into correct position./
I am a little computer illiterate so could someone please direct me to a place where I can see how to make a hooble? I saw the drawing and the foam hobble but was looking for something more like the drawing.
question... If I wrap the chick's leg and body in white guaze wrap to hold the legs in [they will be immobile this way. I would also make sure the vent is not covered.] would that help? I do know the cup method I am using right now is not going to work in a few days as the chick grows.
