Possible Evacuation- chicken needs?

I am currently surrounded by the Northern California fires, just a few hills away - any tips would be helpful on evacuating with chickens. I have 4. I’ve scrounged up a dog kennel and had a test run, all chicks fit okay and ended up all laying down and resting. But if I’m stuck in a parkinglot for a while I need to know other tips to help keep these sweets birds okay. The smoke is horrible, our ranch is covered in ash.

Thanks for anything ❤️

 

We also have a pup and 2 cats, and only have a Scion xD - not an ideal situation for that many animals along with out belongings. But definitely lives are our number one priority
