Memama- about a month ago, my chickens were showing signs of a respiratory illness- I treated everyone with Tylan 40 injectable for 3 days, and everyone is doing fine now! About a year ago, I used the tylan orally, and I won't again, way to much of a pain! Injections were much easier to administer!Not sure if any of you could help me, but I have some sort of illness spreading through my flock. I'm also quite sure they have a heavy worm load (despite my finding nothing indicating it before today). Would you mind checking out my post in Emergencies and sharing any wisdom you might have?
