Did you send the baby for a necropsy? Keep a close eye on your other birds. Temp spikes suck, I hope your eggs are okay. I have six EE chicks that I need to sell but they're so cute I want to keep them too. I had to bring one of my birds to the vet. He is on antibiotics for a sinus infection from debris getting stuck up there.
Poor guy :( I didn't send the baby off to have her checked. I read up on what it could have been and its hard to narrow it down. She was one that was attacked by my older birds so she did have a head injury. I read that it could be encephalitis or a virus (possibly Marek's). Not sure but she went downhill fast. I am keeping an eye on the other babies, not sure what the incubation period is for Marek's but the rest of them are still very alert. They haven't been outside at all but I do clean my coop on a regular basis and something could have come in by air. My babies haven't been vaccinated nor are they on medicated feed but I do put vitamins and probiotics in their water from birth. Not sure if I should switch to medicated or not? It sucks though because she was one of my brahmas and now I'm down to 3. Just hope and pray that they don't get sick. Thanks for listening :)
