I have 10- 7 1/2 week olds (yeah, not "babies" anymore, but wasn't sure where to post but in this section). According to the "decreasing temperature by 5 degrees each week until they get to the normal outside temperature" rule, I believe they would be to where they should be kept at 60 degrees (or a little less since they're almost 8 weeks old), which hasn't been an issue here with our recent temps here in NE Alabama. However, tonight is supposed to go down to freezing or a little below...dry, no or very light wind, so frost is predicted. Do I need to give this age chicks heat on a night like tonight? Does the 5 degree temp reduce rule still apply to this age chicks? I am not planning on supplementing my older flock with heat this winter (after reading here). These "babies" are not in the coop with the older chickens yet (but will possibly be this weekend if hubby gets the coop finished). This is my first time having young chickens & therefore I wasn't sure this time of year what to do. Thanks so much!
