Hello. I saw roundworms in one of my hen's poops and started the whole flock on Wazine for 24 hrs.. Here 14 days later I am doing a follow-up treatment, they are all coop/run bound again for the day (and not happy about it I might add since they primarily free-range... ). Most of the flock have been sniffling and/or coughing for the past few days. So my question is....after I'm done with the 24 hour de-worming retreat can I put the antibiotic in their "new" water tomorrow? I don't want to over medicate them. Or should I wait a few days before I introduce another medication? Thanks in advance!!
