I bought 4 clicks at my local feed store. They were different breeds. Put my beautiful motherly silky in the brother to keep them warm. The two small ones died. Noticed the bigger one making noises when breathing put a few drops of the med in the yellow box. One morning when I went to check on them my silkie was dead. They seen ok. I wanted to take pictures of them and I saw the Grey one with a clear water bubble on one eye. Researched looks like mycoplasma. Very contagious might not die but get the other chickens sick. I have other two silkies here in the city and my flock of close to 30 in the country. Left to spend Christmas in the country. Left them with feed and water. 5 days later they are still alive and look better. I have eggs in my 2 incubators in the city fixng to hatch. What do I do?
