I have a vacation over Thanksgiving or else I would have done fall meaties. I really want to do a batch. Would December in north florida be too cold. We will have an occasional freeze but it doesn't usually dip below freezing for more than a few hours with the average temps being 60 during the day and 40 at night. January is cold with an occasional hard freeze but again might dip to 18 overnight but then back up to 50 during the day. They will be feathered out at 4 weeks right? so after that does it matter that it gets cold? They will have a coop not heated but I'll have them in a brooder til feathered. Will it slow their growth too much or just increase their feed rate? Any info would be good.
