I have a 7-8 month old Tom who is about 45-50 lbs. Found him in the coop the other morning laying down (head stretched out on the ground). It was very cold out, so I brought him inside. If he is sitting (which he does most of the time) he seems fine. Eating, drinking, no drainage from nose or eyes, breathing normal. When he tries to stand up (which is very difficult for him) he stumbles and starts doing this open mouth breathing where his mouth is all the way open, like he's gasping for air. Sometimes it sounds raspy or almost honking. When he sits back down he calms down and breathing is back to normal. He is a bronze and very large...has always had a hard time walking because he is so big. Not sure what to do with him...he is currently living in my bedroom where he is warm and I can monitor him. I live in the mountains of Colorado and it is below freezing outside. Any help would be appreciated. I wasn't sure whether to give him antibiotics (I have Tylan 50) or what to do. I'm not sure if he is ill, in pain, or dying. He is a pet, not going to eat him. Thank you in advance!
