If you can run a heat lamp so thier water doesn't freeze at night, it should be warm enough. You can put vaseline on the little roo's combs to keep them from getting frostbite when it's really cold.
Oh- I made a mistake before- the last 2 are crele- the one isn't mille fleur.
Very cute! Quite a range of colors you got too!
Barred
Birchen
No sure- maybe buff columbian?
Barred
Mille Fleur/Spangled
& Crele
Sometimes the same color will have different names depending on the breed- like mille fleur for d'uccles vs. spangled for sussex.....
