Hello Everyone! I am a NEWBIE chicken owner!Never owned a chicken before in my life before 2 months ago! This morning I noticed 2 of our hens with sneezing, a swollen eye, like a mucus coming out of the nose maybe, and what sounds like coughing. These hens are mixed breed chickens, I don't know how old they are cause i bought them this size. This is also the first sign of any trouble. They are good eaters and good layers. Our chicken pen and yard has just been built and we keep it cleaned out at all times. There's no stacks of poop is what i am trying to say . We keep the water source off of the ground so it's not full of poop either. and it's changed daily. And they have feed out for them at all times. Nothing I own goes hungry, (including myself) LOL.. Any advice, thoughts would be so welcome! Oh I should add we have the 8 full grown hens, and 36 teenage chickens in the pen.. Thanks so much in advance for your help! Sincerely,, Elainew..
