Hello, I have a flock of approx 70 standard Hens, mixed breeds. I recently added 8 young hens, one died about 1 wk later (none seemed ill at anytime) A few days later, I another hen died (approx age 2 yrs) My flock seems subdued with decreased appetites. I hear occaisional "sneezing type" behavior. No diarrhea, or other obvious signs of trouble. Egg production is WAY down. I think my flock has a CHICKEN-COLD!The hens are housed in 2 large coops and have large outdoor runs. Feed is a standard layer crumble, morning corn grains, and usually daily greens/fruit & veg of some sort. Water is pentiful and fresh daily. I've had a flock for about 5 yrs and not experienced illness yet. I would appreciate any help in assisting me with possible treatment. Thank-you all!
