I am about to get 4 to 6 chickens this weekend. I know the lady and have worked with her and her chickens before. Do I still need to quarantine the new girls or can I just use the time at there old place as a quarantine? We both live within 5 miles of each other and the flock is health. I understand quarantining chicken you dont know but I am not sure about ones I do know. Also I really dont have a place to quarantine 4-6 chickens that are already laying.
