I am new to chicken raising and am looking for some advise on Merek's Disease. We have always bought hatchery chicks with vaccinations already done. This last year I let the kids hatch and raise a few birds and also brought in a few birds given to the kids by one of their 4-H leaders. I just lost 2 birds to Merek's Disease this week. The ones from the 4-H leader. I am guessing my non vaccinated home hatch birds will more than likely fall subject to this disease as well. Is there anything I can do to help prevent this? My second question is this, We are going to set up a hatching and brooding room in our new barn. I raise my birds "natural" and on organic feed. I am going to vaccinate for Merek's when we hatch chicks so I don't have to put the kid's through this again. So, will this effect my "natural/organic status? I hear mixed opinions... And does anyone have a link to somewhere that I can buy the vaccine to administer ourselves?
