G'Day Experts! Hope some of you have seen this before. One of our 23 chickens, a Sussex about 5 months old, is sick. Last night I saw her 'yawning' on her perch, thought she was tired, this morning she was definitely sick. Vent looks normal. Occasional sneezes, I can't hear any gurgling in her breath. Poop is very watery. Other birds appear to be normal in all the above respects. Wasted a couple of hours on the phone with the State (heard the words 'we used to', many times. Tried to find a veterinarian, there don't appear to be any that would examine and treat a chicken (Vermont is a resort area). My wife went to the farm boutique and bought Oxytetracycline Hydrochloride. No instructions on how to administer, except that the envelope said that you need a 'water proportioner' which the boutique did not sell. I did my best to guess at the proportions, put it in her drinking water. She is now eating and drinking a bit. Searched topics on this forum, lots of interesting data but nothing conclusive. For the moment we have her isolated; I'll put together a box for her; should she spend the night in a warm place (we go below freezing overnight)? I would love to take this bird to a vet. Although with clear instructions I might be able to manage, I would vastly prefer a real diagnosis. Please advise, thanks in advance ! -Rob PS Our 23 chickens live in an 8x10 coop with ample roosting space, but spend most of their time outdoors. The bedding is shredded pine or maple (not cedar). It has been changed recently.
