Thank you. It was awful, especially when I was feeding great feed, I kept treating and treating for parasites, and was powerwashing and delousing their coop weekly, but they were still dropping.So sorry about losing your birds, that must of been devastating, also not knowing what was causing it.How did you realize it was the feed?
I figured out what it was when I mentioned that all of my birds were thin, and was recommended to switch from Master Mix to a turkey feed temporarily, and most started improving. A few more were too far gone by that point, but most have rebounded nicely, and I now feed a 20%.
I am by no means saying that FVF Master Mix is a bad feed, but the problem is that because it's not a homogenized feed the dominant birds were picking out the"yummy" but less nutritious bits, and leaving behind the "yucky" nutritional pellet which in turn was eaten by the less dominant birds, and it's far too high protein to be a sole ration. I'm definitely sticking to homogenized feeds from now on!
I have two that are at my house right now for further monitoring, because I have a mild respiratory thing going through the silkies, and those two were hit hardest. I wanted to keep them in an environment where I can ensure they are both eating while being medicated, plus I can keep an eye on their weight. It's kind of fun having them home, they talk to me!
Clearly lighter than the other two which are black. Their father is recessive white, which means he could be hiding anything genetically.
