Some of my chickens are sick. It's not coryza as there's no foul odor... so I'm assuming it's CRD. They've been separated for around 5 days now from the flock. They all got shots of Tylan 200 for 3 days. Though, I'm kinda worried... should I have used Baytril for this instead? We had the Tylan readily available, so that's what we used. My question is -- how long should I keep them separated from the others? They're all doing remarkably well - I'm glad I caught it early. I know with Tylan, you shoud wait at least a week before starting to consume their eggs again (but with this nasty cold weather, we haven't been getting very many eggs anyway).... should I wait to reintroduce them until then? Are there other things I should be doing to prevent this from recurring and/or spreading?! Just checked on them & they're all looking great. I'm not sure if I should try & reintroduce them today or not. Thanks in advance, everyone!
