So sorry to hear about your loss.![]()
I thought a couple of my young ones had it last year, but after treating them and reading this thread and some of the Marek's threads, I decided it was probably a vitamin deficiency. Both of them were from the same hatch and back then I used the medicated feed. One was about 4 weeks old when it came down with it, the other was about 17 or 18 weeks. I lost the younger one before I learned about the vitamins, but the other pulled through and is doing fine. I now use only non-medicated organic feed from hatch on and have not had any more problems.
How old were yours? Did you start them on medicated feed and were you giving them vitamins?
Mine were 17 weeks old. They had been started on the medicated feed, but when I learned that medications were causing issues for SFHs I took them off it - a number of months ago. I'm fairly certain it was not a vitamin deficiency as I feed fermented feed and they free range all day.
The nearest place that could do a necropsy for us is 90 minutes away, and would have charged an arm and a leg, so unfortunately I couldn't have the necropsy done. I don't know for sure that it was Marek's, but I do know that both birds presented nearly identical symptoms. Inga's symptoms came on quickly, but Frederic's came on slowly. Weird!
It makes me wonder if there are vitamins and/or minerals that are in good supply in the soils of Sweden that are lacking here in the states.![]()
I'm quite certain this IS the case! This is one of the reasons I started feeding fermented feed - it allows the birds to get much higher nutritional value from the feed. Yet - not knowing the exact difference in minerals in southern Swedish soil, I'm sure that is where many of our birds become deficient.
I'd love to know what minerals would best help these birds.
Oh no! If he dies, have a necropsy done so you know for sure. I'm so sorry you are going through this.
Mentioned this above

That said, if this was Marek's, I feel better knowing that the rest of my flock is resistant to the disease which would indicate naturally stronger genetics in those birds - totally worth breeding for this kind of resistance!! Of course I'm keeping my fingers crossed and prayers flying up to heaven that none of the others come down with it, but so far, so good!
So - over the next days, I'll be researching naturally occurring minerals in southern Sweden, and whether or not Marek's is present in Sweden.
