Is my compost bin meant to have condensation on the inside?

It's layered brown-green inside and in the sun for a few hours a day.

I only filled it on Saturday, should I go and mix it now?

yes totally normal.
just leave it.

I don't think to mix it too soon. If you are really lucky, and you put plenty of material in at one go, you MIGHT find it is getting warm underneath. Which means bacteria is working, and starting to make real compost (rather than smelly sludge, which can happen)

Is it standing on bare soil, or does the bin have a bottom? Best on soil; also you might get earthworms and slowworms (the tiny baby ones are lovely, and super to show to children.)

Well, if the compost inside is warmer than the outside of the the bin then that's a good sign!

It's on a base plate, I can't have it on bare soil unless we put it in the front garden.

It's sooo tempting to go and have a stir, when do you stir them?
