My flock like many out there are exhibiting signs of sneezing and runny noses and seems to be spreading quickly. I have 12 hens I started yesterday on poly vi sol (non iron) 3 drops and a few drops of vet rx Also added both to waterer After researching on here, I went out and purchased the big bottle of Tylan 200 at TSC for $29.99 last night, just in case haven't opened it yet! However, I have read people on here get the best results by injecting 1/4 - 1/2 cc per bird in the breast for three days Where/How do I obtain syringes to do this? Do I need a new one for each bird, if not how to sanitize? If I cannot get syringes, my other option is 1cc (1mL) down the gullet for three days as other folks have had luck with on here. What is the time spacing between doses? 12 hours, 24 hrs, 48 hours? Thanks so much for your help!
