3 chicks staying outside all night?????

[rnjoyce]

I have 6 RIR, 7 months old, laying, and healthy. They have gone in their coop every evening, until recently, 3 of them stay out all night. Does this mean anything? Or did they just decide to change their habits for some reason. Any answers or ideas would be appreciated, otherwise, I'll stop worrying about them.

It's normal for them to go other places but if something gets them in the night thats not good and that is why we put them in the coops.They some times will sleep in trees like they would roost in the coop.

Its getting down to the 30's at night here and all 23 of my chicken still sleep on the outdoor roosts. If it were me I would go in but then again I'm not a chicken.
