Hi I have two cute adorable bantam chickens. They were my first. I now have 12 chickens and 5 ducks. My little girl seems to have a wheeze I noticed the other day her chest was really puffed so I googled and it said she may have impacted crop. It was really full so I tried to give oil eggs and water and started the massaging daily. When I massage her breathing change. She open her beak open and seemed like she was wheezing , coughing and sneezing. Her crop is better. I also took the feed away added more grit and water at night in the coop. So the crop has reduced but the little sneezing coughs and wheeze remains. She is eating, dirt bathing and running around just fine. No mucus ,no bad breath. I have also added apple cider vinegar. I made a vet apt but worried that he wont be able to find out what wrong. Do I need to be worried?
