Hi BYC peeps. I'll cut to the chase: I had two hens and one suddenly died a couple of weeks ago. Worried about my BO, Flo, being lonely, I bought two pullets a few days later and quarantined them in their own run; one died a couple of days later but the other has been fine for about 10 days now. Four days ago I got three more pullets from an organic farm and added them in to the second run with the pullet I acquired a week earlier. I've been adding vitamins/electrolytes and even ran Sulmet (sulfamethazine sodium 12.5%) in everyone's drinking water for a few days (changing daily). This evening I decided to let Flo and the new pullets free range for about an hour under close supervision. It went relatively well, then tonight I decided to read up on integrating chickens (something i clearly should have done long ago) and have been reading that I should have quarantined far apart for 30-45 days!!! Oh no! Given it's too late to do this correctly, is there anything I can/should do to mitigate the chance of potential infection from the new pullets? Should I take everyone to an avian vet for evaluation/treatment? Are there any treatments i can do myself? Or just hope for the best? Any advice is appreciated!!
