I have sixteen 4-week-old pullets out in the coop. I got them from McMurray as 1-day-olds. Everyone doing fine. Just managed to get three 3-week-old guinea keets that were hatched locally. For the moment I have them quarantined in the brooder that the chicks moved out of, out in my mudroom. I'd like to move them in with the chooks ASAP. How long do I need to quarantine the keets?
