With Mareks you would think there would of at least been one symptom. I don't think chickens usually just drop dead from Mareks without any signs
I don't think that they always show symptoms. I think Mareks is actually the most likely culprit as it is common in young chicks and doesn't always show symptoms. Were the chicks hatchery or breeder? If they were hatchery then they were probably vaccinated but if they were breeder they probably not.
On the Mareks FAQ article on here they mention it doesn't always show symptoms.
There symptomatic and asymptomatic. Asymptomatic, not showing symptoms. I just find it odd that all the d'uccle would be affected and none of the ameraucanas and not a symptom.
I realize that, but it seems a little soon to be jumping to conclusions of Mareks so soon. Many diseases interlap symptoms and mimic each other
I have to say, that having done a ton of research. It is EXTREMELY rare for mareks not to show symptoms. At the very least, the chick should have shown dilated pupils, ruffled feathers, or lack of control before it died. Also, the poop most likely would have been runny and green to show what the disease had been doing on the outside. But, of course, there is the very rare time when the birds do just fall over and die from it, but I don't think that this is what alibra is dealing with.
