I know this probably belongs in the disease section, but it only seems to be affecting my turkeys. If a moderator thinks this would be better off in that forum sub-section, feel free to move it. Out of four turkeys I purchased this spring ( a BB Bronze, 2 Bourbon Reds, and a Royal Palm), three have died of the same symptoms. The BBB and one of the Boubons died in the beginning of July, the Palm just died half an hour ago. The symptoms are as follows: Turkey starts defecating a yellow, wet diarrhea. Bird becomes listless, starts losing its balance, then its ability to walk, and finally dies suddenly of a heart attack. The BBB had symptoms for four days before death; the Bourbon, two. The Palm showed no symptoms this morning when let out, and been acting normally yesterday. My dad found him laying in the ditch that runs along the property and hour and a half ago. Now he's dead. Bird showed additional symptoms after he died - there was a thick, tannish mucus coming out of his mouth, and he had rigor mortis within 15 minutes of dying. Note: These are the only symptoms these turkeys have had. There has been no change in their appearance or the color of their skin after getting sick and dying, and all were perfectly happy and healthy before showing symptoms. I also have chickens and ducks, all free range, and there have been wild turkeys living in this area for the last thirty years, and have been frequent backyard visitors. I also live in Michigan, and just like a lot of people in the U.S., we've been having hot, humid weather. One more thing: there is a CAFO dairy farm across the road from us that shares the same ditchline. For the first two birds, I thought they had mild coccidosis that had been made more vicious by the 100+ F humidity heat index temperatures that hit us in early July. The sick birds were given treatment doses of Corid; the rest of the birds were given exposures doses of the same in their drinking water for the following four weeks. The Corid didn't do anything for the sick turkeys, and it obviously didn't help the Palm. What else could be affecting them? Something they ate? Drank? What? I don't want to lose the the last of my sweethearts to whatever this insidious thing is. Help. Thank you.
