Guineas spasming and then dying?

[Desertroserobin]

I have several guinea meets keets that are around two months old. Today I found one in the coop dying. He was awake but seemed to be seizuring or unable to control his movements. There was no trauma or damage. I haven’t had any issues before. I took him inside and tried to figure out what was going on but he died a few minutes later. Now I have a second one doing it. Can does anyone know what can cause this?

I'm sorry for your loss. Maybe they found and ate something poison.

Sorry for your loss. I would look over your feed for any signs of mold, such as a bad odor or bluegreen color. What have they been eating and drinking? Have there been any runny poops or hot temperatures? Could she have eaten something dead or in a compost pile? If you have the body, you could keep it cold and send it in to your state poultry vet for a necropsy. Here is a list of state vetsto contact:

They’ve been eating an All Flock feed, although I actually think this bag might have been some type of layer feed. But I just opened it a few days ago. There’s no signs of mold in it, although we did get a bag full of mold from this place about a month ago. We caught it before feeding any of it. These guineas are still in my growing out coop and aren’t let out to free range yet, so I don’t think they could have gotten into anything. One thing I didn’t think to mention last night, we re in the part of Oklahoma that got hit with major ice storms last week. I lost four of this hatch in one day but I assumed they must have gotten wet before it froze and immediately moved the rest into the brooder in the garage. I moved them in Wednesday morning and haven’t lost any since. Then lost two like this yesterday. I do have a few older bantams in with them, but I’ve never noticed any problems between them.
On the necropsy, in my state they’ll actually do so many per person for free. But I used that up last year when I lost several birds and couldn’t figure out why. Those were chickens with very different symptoms though. I’ve never seen anything like this.

My 5 year old is the one that found the first one and it was horrible.
