At first I had three chickens, to of them unforunately died... So, we decided to get the remaining one 3 new companions. We heard to hole "keep the seperate, but still somewhat close" thing and did so for about a week. We just put them together today, they were pecking and stuff like expected, but the original chicken has been making this strange sneezing sound. Im really conserned, we have been putting a small dose of probiotics in their water hoping to prevents other disease. Any idea what it is and how to cure it? Any help is apperiated.
