Looking for some guidance. Please help! Pics below This morning one of our hens had so much mucus around her beak and one eye she couldn’t open them. She is weak and obviously having trouble breathing. She will take water with AVC when I give it to her using a syringe. We have cleared the mucus from her beak but she’s not eating. She’s having trouble holding herself up but can stand. We have separated her and put a heater on her. Yesterday they were all active, eating and drinking though we were hearing a lot of sneezing a week or so ago. Weather has been very wet and cold. We’ve had a lice/mite problem we’ve been working to eliminate. Could this be related? Could it be a crop issue? One other Hen is gurgling when she breathes and didn’t want to come out of the coop this morning. She is normally very aggressive. I’ve added AVC to their water and have been giving probiotics and garlic for a week or so. We have 5 hens and we’ve only had them for two weeks. What should we do next? Antibiotics? Sterilize the coop? treat them all with something? We prefer to stay away from antibiotics but are willing to consider it if we could save their lives. Please help!
