We are wanting to adopt 5, mature, barred rock hens and integrate them into our existing flock of 14 mature hens. I do not have a holding pen big enough to quarantine all five hens. Here is what I am wondering. Could I take one of the barred rocks and one of my existing flock and quarantine the two hens in a cage together for a (is it 4 weeks?) period of time? Then if neither of them gets sick would it be safe to go ahead and accept the other ones and introduce the remaining 4 barred rocks into my existing flock without a quarantine period? The barred rocks have been well taken care of and do not have any history of illnesses but of course my concern is immunities or lack of to different strains of coccidiosis. If this approach is not advisable, do you have any other suggestions? Thanks so much.
