I have a lot of chickens, few of my yearling chickens started with bubbly eyes and weezing - no discharge, Vet gave baytril,eye drops,told me to give Tylan. Stool sample and some expensive test showed nothing.They got better but sometimes reacures in my other birds, even ones in other pens. Then I noticed some of my silkies and bantms losing weight,getting weak and having trouble standing. Stool test showed worms so I wormed each chicken with fenabenazole, then again after two weeks. They still seem thin and some are still weak and have trouble walking. I lost two after much trying and effort to keep them eating. Vitamins in water, wet mash, scrambled eggs etc. Vet doesn't open till Monday - I'm at a loss. Put all on Sulmet now, hoping to help. Any one have any ideas???? They eat chicken grower, 3 grain scratch, have feeders always full. Next case --- Chick born fine, 2 weeks later noticed head cocked to side looking up, now head turns all the way around eyes facing ground cheeks facing sky. Eats and drinks but walks in circles. Put a neck brace on him-he is not happy!!!! Can turn head back normal but often stays in upside down position.?????? Any one else had this problem???? I feel like a bad chicken mom, my horses seem easier right now.
