We saw some 4 week old keets at the feed store today. So we picked up 4. Have we lost our minds? We already have chickens. The guineas look pretty well feathered out. From what I have seen online, they are supposed to be able to go outside around 4 weeks? We are in Texas and the night temps are around 60 right now. They will be in a tractor-style coop with the coop on top and a run on bottom.
