Frost and chickens water.

I find it difficult to align the door up to the holders which you slide the locking pin through. 

 

When unhooked from the holders the doors are wonky slanting down. 

 

I'm not sure if this is usual or I've just not installed the run correctly. 

 

I'll try take a pic tomorrow.

Make sure your run is as level as possible and you clip the doors to the run on the top and bottom of each door. They do slant a bit when they hang free, but should be able to align up with the holders.

A soft underground won’t help, a solid base like paving slabs will be better.

I've got them on the grass currently. 

Thinking it's better for them having a rummage and what not. 

Though I've heard people recommend slabs with woodchip over. 

What do you think is best & most practical?

Grass is very short lived with chickens and in wet winters it can turn in a muddy mess.

I have mine half on earth, but dug in slabs where the run rests on border pavers. The rest of the run is on paving.

As Cattails says, it depends whether you plan to leave your run in one place. If you do, then the grass won’t last long at all before it turns to mud.

Covering your run will help the mud situation too.  Prevents chickens developing trench foot!
