Just wanted to provide an update. Of the original 8 chicks that hatched, 2 are left alive, but they are experiencing symptoms. I've got them on water soluble Tylan antibiotics and am giving a couple drops of Poly-Vi-Sol per day to help them live as long as possible, but I'm sure they'll die like the rest.
A list of the things I've tried include:
1. Corid in the water
2. Probiotics & Electrolyte packets from
TSC
3. Injectable Tylan 50 given orally
4. Minced garlic in the water
5. Apple Cider Vinegar in the water
6. Changing feed and water daily
7. Soluble Tylan in the water with Poly-Vi-Sol
-The first sign is always an increased breathing rate, followed by pasty butt. They continue to eat and drink with the others for a couple days.
-The next day or two they begin to sit there with their eyes closed, start to have trouble walking, and the breathing becomes faster and faster. The poop becomes runny, but there is no sign of blood.
-Then they start to breath with their mouths open, panting, even though they are not hot. This all happens 6-10 days after hatching. Their eyes are not crusty as far as I can tell. They chirp when they breathe.
If it was MB, I would think there would be improvement with the antibiotic treatments.
If it was Coccidiosis, the Corid should have taken care of it. There is no blood in the poop.
I believe it is either
Infectious Bronchitis or Infectious
Laryngotracheitis, but it could also be E.coli as Eggcessive suggested.
If anyone has a suggestion about another form of treatment, please let me know. I'd be happy to even save 2 of them.
