DH moved my oldest babies out of the pen today. They seem to be doing ok, but I think maybe it's still too cool for them. They have been without a lamp for about three weeks now, and have done well. Temps are running 60's at night, high 70's during the day. Is that too cool for them? They are between 7-8 weeks old and are fully feathered. Am I just worrying over nothing? DH says I am. He says they will be fine, but I don't know.
