Young chickens not going in at night

I don't think letting them stay out is very dangerous, but you want to be very sure that your run is entirely safe. If your neighbor is unwilling to put them in, you might just want to check for gaps or holes in the run before you leave. The temperature sounds fine to me. Have they successfully stayed overnight in the run before?

They haven't slept outside before

The main risk is foxes but I've not seen an in my garden

It could be that they are avoiding Pippin but there are plenty of other places for them to sleep

I'd just keep putting them in and see if they can find a place they are comfortable.
