No signs of respiratory infection, sneezing or nasal discharge. Has any one had this kind of thing happen with their Marek's birds? She's been a little slower than normal the last couple of days. She was eating a little bit yesterday but not anything today that I've witnessed.
ETA: I tubed her with my cocktail of tylan and oxytetracycline. I didn't mix in much water since her crop already has a lot of fluid in it. Not much I can do until tomorrow - will wait and see if she looks better or worse. Unfortunately I have to be at work at 5 a.m. tomorrow.
As I expected, the pullet didn't make it through the night. From the way she was breathing yesterday, I suspected she wouldn't get better. I always want to give them a chance though.
Ironically, she has always been my biggest, strongest chick. She was a huge bird all along. Her dad was a little legbar and her mom was a medium sized sussex, so I didn't expect her to be large. However, she grew quickly and always seemed strong. When she got sick, she went down hill quickly.
From the Marek's hatch I had one cockerel that was also very large and even aggressive. He was so much bigger than is brothers that I also thought he would be stronger and superior. He was the first cockerel to get sick from Marek's. He started open mouth breathing and his comb turned purple. Two days later he had a seizure and died. I guess bigger isn't always better.
I'm just about out of unvaccinated chicks. There are two australorps, one little redstar cross, and the sister to the pullet that died last night. It is hard to believe that a couple of months ago I had almost 40 chickens and now I have 20 plus two 11 week old pullets. The younger ones are all double vaccinated. If they get sick I'm throwing in the towel!
