Hobbled Chicken?

[Sanderlina]

We put hobbles on our little crooked one and it's not particularly happy (I don't imagine it would be) though is eating and drinking. I sort of fear it being pecked to death overnight though - those of you who have chicks, would you leave it in with the others or try to make it it's own box?

I don't particularly want it getting cold, but I don't want it to die either. I have some little foot warmers and a space heater I can stick with it in the short term but that's a terrible long term solution.
