It could be Mareks. there is ONE sure fire way to know.... did the eye color change? I had a cockerel get it and he survived a long time and if they survive they can pass on some resistance to chicks. Another thing I see more often is cock/erels will be too rough and cause a leg issue. They can recover from it if caught early enough and removed from the cock/erel so she can heal.

We also have an incubator so could possibly hatch some out (that's how we built the previous flock). Also, have you used the online hatcheries? McMurray, Ideal, Meyer, etc?
