Hi I am a new chicken owner , live outside of Los Angeles, and have (6) 7 week old chicks (silkies, Easter Egger, and buff Orphington) it's been very cool where I am lately- high 50s/60s during the day and low 30s in the middle of the night and early morning. Is it safe for my chickens to be moved in the coop? Do you suggest a heat lamp? One in the coop? Or coop and run? Please tell me your thoughts... I also don't know if I am supposed to close off the run at the beginning..? Ps I am starting to wean them of the heat lamp in my house. Have been doing no lamp during the day and just at night. Any advice would be greatly appreciated!
