Um... A little embarrassing. Is it ok to cook chickens who have respiratory issues. I mean to eat or at least to feed to the dogs? My birds keep coming up sick and I'm getting tired of culling these birds and just burning them. Pretty sure it is coryza or CRD..?? Not much is helping to clear it up, but to cull. Just wondering. Seems like its such a waste. About to give up chickens all together. I have much better luck with ducks!
