Hello folks!! Usually my hubby is in charge of the chicken research as I'm wrangling our one year old, but I have a rather involved question, so here I am to type it up. So as he posted yesterday, we lost one of our girls that we suspected to have been dealing with the blackhead disease for quite some time, before we received her back from foster once we finally got our land established, house built & chicken castle set up. All of our research suggests that even if this wasn't the case, the best bet is to go ahead and treat the flock since we have a combination of 4 different sources of girls/rooster out there that we have enlisted in building our flock. I have checked with all the previous owners and no one has dewormed and our ages run 8 months-3 years old. I suspect that everyone started on medicated starter feed, but that's it. So for starters, we did some Wazine in the water tonight for basics & as that was the only one I could get from the local feed store. So in my research I'm thinking, it will be very best to follow this up with a dose of Safeguard (Fenbendazole) which will not require a 10 day booster due to the prior Wazine treatment, they are getting today. Now to complicate matters, I understand that coccidiosis is another concern and although not as likely the cause of our fatal loss yesterday, definitely something we need to address since we have so many different origins for our birds. Does the Wazine & Fenbendazole combo cover us, to include cocci? Or do I need to go ahead and run a round of Corid with them after the Safeguard? We are doing a heavy withdrawal for 10 days from the latest round of dewormer so that's not a concern. Just got our last 4 girls in yesterday anyway, so they won't probably lay for us for two weeks to begin with. So in a nutshell... if concerns are that we lost a hen to blackhead disease, and want to be covered for coccidiosis as well due to 10 birds coming from 4 different sources, is Wazine + Safeguard enough? Or should we cover all bases and go conservative on the new flock with a Wazine + Safeguard + Corid? We WILL NOT be combining any of these treatments, we will be spacing them out a couple days apart for each- just for clarification. Thank you in advance chicken wranglers! Steph.
