I have 6 chics from about 7 to 8 weeks old. There are a few that by size seem like they should be older to me... I want to leave them in their hen house for the day . the weather is high 72 and low 63 by the time i get home to bring them back inside... I keep them in a bunny cage at night since it gets 60 and below... From what i read they cant or shouldnt be left under 65° till closer to jan when their age is 20 weeks plus... Ill take any advice yall can give me.
