I know this is an older thread, but I just had a huge outbreak of CRD in my flock and have lost almost 20 birds in the last week. I immediately started treating with Duramycin when I heard the first coughs, but I know it doesn't do much of anything, however, it was all I had on hand and figured something was better than nothing. The next day I got some Tylan 50 injectable and started treating. I started losing birds right before my eyes, and let me tell you, I am a tough woman who my kids even ask if I EVER cry, and I almost started right then. I ended losing most of one pen of Dark Cornish that I raised this summer. I had to put down a few that I knew were going to keel over (literally since they end up having heart attacks due to lack of oxygen and flip on their backs dead). I have over 200 birds, so this got scary really fast!
The Tylan still didn't work on some, even though they had 2 daily doses of 1 ml each administered orally (this is how I found to treat my turkeys when they got sinitis). Today, I rejoice that I did not go out to any dead birds. This is the first day in almost a week. Catching every bird to give them Tylan is a pain the ***, but worth it when I go out and see once sick birds eating and running around again.
I did find Denagard and read up on how effective it is. Funny, my husband works for Novartis and it would be nice if I could get a discount, but just glad it got here quickly and I am putting it in their water today. Just had to check how much, so thanks Pips&Peeps!
This is my business. I cannot afford to lose this many and not act on it quickly and effectively, so I hope this is going to clear up this crud. I do get wild birds in the coops, and it amazes me the small holes they find to get it. I also pasture raise my birds to the extent it is possible, but the breeding pens are being confined for the upcoming hatching season. I know my culprit bird(s) and they are gone. Hopefully, I will never experience something so devastating again, but if the Denagard works as well as I have read, then I am keeping it on hand and doing a preventive treatment at least once a year.
I want to add, the weather we have had here in Minnesota the last couple of months has not helped this kind of stuff. Even my open-air coop has felt damp and stuff the last couple of days. The fluctuations of warm and cold have just wreaked havoc with the birds, and so it is no surprise that when this whole thing started it just spread like wildfire.
I will post how everyone is doing in a week. So far, the Tylan does work in making them act better, but I have to try and make sure that there is no lingering MS/MG for my testing for the 2013 season. If I can't pass to get my NPIP this year, I will be crying.
Thanks to all of you who are willing to share your knowledge and help those of us with less experience.
