No i didn't quarantine the 2 new birds I am knew to chickens and didn't know that was required but def know that I will b doing that in future purchases.i think I will mix in with the water for all the birds befor they all get sick . Just wasn't sure if the ones with no symptoms could have antibiotics . I have 3 older girls that are laying just almost everyday do I need to refrain from eating there eggs . And if so how long do I not eat them and how long do I leave them on the meds .
