Let me ease your mind, it isn’t Mareks. Mareks is not transferred vertically (through hatched eggs) but horizontally (through contact with dander from infected poultry). If your newly hatched chicks were exposed to Mareks right now it would take at least several weeks to show signs and symptoms.Thank you. I certainly hope it's not Marek's. I had to assist this one in hatching, as well as two of the other three that hatched. Ironically the one with deformities was the only one that didn't need an assisted hatch. The other two that were assisted appear fine and are up and running around, causing trouble as chicks do. This one may just be weaker or have something wrong internally. I hope it makes it, but I'm not sure. I'll try everything I can though. I've only hatched three times and I've had such bad luck each time... I feel so bad for these babies this time around and like it's my fault. It makes me want to give up on hatching.
