First time posting! We have 50 Rock Cornish X, 6 days till processing. We've culled two so far to CHF (we believe-labored breathing, purplish/blueish skin, combs); they were culled approximately two weeks ago. Today, one hen, has labored breathing, with a 'gurgling' sound. Have never heard that before. Still eating, drinking. 8 weeks old on Friday. No runny 'nose' or eyes...yet? They are being raised in a chicken tractor and have been on the field for almost 5 weeks now. We live in Southern Vermont and these chickens have survived Hurrican Irene and a very very rainy autumn. Extraordinary efforts were done to keep them dry....hay beds changed in the tractor every day, tarps to keep the rain out (removed when sunny or not raining!). I guess my question is, can someone give me an idea what this chicken has? Is it pneumonia, bronchitis? If it survives till Saturday, is it edible? Thank you to all!
