Hi. We just got chickens several months ago, so all this is new to me. I have 2 large buffs (? i think), that i got and was told they are about 9mo old. They have been laying eggs about every other day and acting fine. Yesterday i didnt get any eggs, today either. When checking around the coop i noticed one has a swolled eye - its swolled shut and seems like it has some discharge comming out, and also a runny nose. The second one has a runny nose and slightly puffy eyes. They aren't as active either. we are in fl and its been really warm here for a while, but last 2 nights where cold, got down into the 40's at night. Did they catch a cold? Or is this something else. what can i do or give them. I would prefer to stay away from antibiotics if there are other options. Should i seperate them from the rest of the chickens? Also, are there any websites i can check out to learn more about chickens, care, illness.... all kinds of stuff. Thanks for any/all help.
