Help! I have 41 birds… 37 chickens and 4 Guinea fowl. I had a hen die exactly 2 weeks ago, she had a runny nose and raspy breathing. I immediately cleaned out their coop, feeders, and waterers. I kept checking my other birds for nose drainage and breathing. 2 weeks later and I now have another sick hen, she is in better shape then the last but she has a runny nose/raspy breathing. I isolated her inside & gave her extra vitamins/electrolytes/etc. What is happening? Anything else I can do for her? For the other chickens? Help…
