Crowing
Gosh dang, that worries me so much but I'm really glad you spoke up. This year has been horrible, I lost one of my chicken coops where these particular chicks were going and I had no choice but to integrate them into my main free range flock. Everything was so unexpected I was unprepared. I want my cockerels in my rooster flock, but they're a little too small yet for my big guys.Marek's outbreaks are triggered by stress. Integration of youngsters is a major stressor both for the youngsters and also sometimes the older birds..... too many adolescent cockerels in the flock is another major trigger.
Your lame ISA may be due to an injury but she may also be having a Marek's episode. The disease can lie dormant for months or even years in an infected bird until an outbreak is triggered.
When you mentioned that you had a skinny youngster in your original post, my first thought was Marek's but as others suggested it could certainly be as simple as the youngsters getting bullied from feeders, so I didn't offer it as a suggestion but now that you have a youngster showing more classic paralysis, it certainly becomes more of a possibility.
I am pleased that you are getting a necropsy done. Unfortunately the PCR testing for Marek's will take time to be processed by the lab, so you will probably get a gross necropsy result pending those lab results which make take a week or two to arrive.
I hope I am wrong, but since it is such an incredibly common and widespread disease, it is the most likely diagnosis.
If this is Mareks, have I already spread this to my chicks still in the brooder? Its in the garage, but I'm of course going in and out all day.
