I haven't had chicks for awhile and I feel like I have forgotten what to do in regards to taking them out to the coop. I feel like I waited till they were 8 or 10 weeks old but I can't remember... I have 9 baby chicks that will be 5 weeks old on March 1st and I was thinking of moving them to the coop with no heat lamp. We live in San Diego so its been in the high 40's at night and 70's in the daytime. Do you think they would be ok? We have 1 hen and everyone has been getting along ok. She will peck them here and there but not too aggressively. I was thinking of putting the heat lamp into the coop for just at night but it sort of worries me.
