11 chicks dead in 1 week

[RaventheChicken]

I'm an experienced chick rearer. I've rarely lost a chick to illness. But this year, when I got a dozen chicks, they were dropping like flies. Only one of them has survived. Symptoms started with toes becoming weak and curling all over the place, mostly curling inward. Later, as they got weaker, they were unable to eat and always stayed under the heat lamp. They developed severe underbites to the point where they couldn't eat. I put a little bit of gatorade in their water for electrolytes, and they were being fed MannaPro medicated chick feed. I also hand-fed them warm sugar water. The one that survived still has curled toes and a slight underbite today. What the heck happened??

I am not sure but it could be Marek's. Did they have trouble walking and moving around as they got closer to death? What were you feeding them? What breed were they?

I just saw your other post about your duckling. This is all odd. Perhaps some underlying disease they all have? Perhaps you have a bad batch of feed?

Try giving vitamin supplement, expecialy Riboflavin. A deficiency will cause toes to curl and can lead to death. Poly-vi-sol without iron, a drop to the beak 3 times a day, since it is water soluble the body will only use what is needed and disgard the rest. I hope you are able to save this one!
I only suggest this assuming the chicks are very young and may have had a vitamin deficiency when you got them. Mareks is another possibility but unsure if affects very young chicks again assuming these are very young.
