OK, so I have been reading the posts and replys about coughing chickens and the common additional symptoms... My birds (4 of 25 so far, 2 roos and 2 hens) have a cough, one seems to have fairly labored breathing at night and another of the 4 sound very pflegmy (sp?) in his neck/throat. They do not seem to have any other symptoms like crusty, weepy eyes or runny beaks. Their activity level is normal, both Roos have not lost any interest in the hens and everyone is eating normal amounts. They are between 20 and 22 weeks old, just starting to lay, although sporadic at best. Poos seem fairly normal given the range of foods they eat, a combo of organic feed, free range and veggies from the garden - mostly tomatos, cukes, crook neck squash and zukes. The one thing they do like to nibble on that seems odd is the tomato plant leaves. I have read here that they can be toxic...I see an occasional runny, liquid poo, but it looks like the normal range of runny and color when compared to the pics on the poo link (gotta love that!!) Coop and run have a mix of pine shavings and dry field grass cuttings from our front pasture - no fertilizers or pesticides used. Coop is secure and dry with good ventilation. I do not see any evidence of bugs or mites or worms although I have never wormed them as I am trying to keep their lifestyle/eggs completely organic and chemical free. We have just come through a bout of wet, warm weather after some pretty hot weather and they do go out in the wet to free range. Have I missed any info needed to help diagnose?? I thought I would start with adding the Organic apple cider vinegar to their water and see if that helps clear up the???? Any suggestions?? I love this forum, there are sooo many knowledgable and helpfull chicken lovers out there! Thanks for anything!!
