I got 3 turkey poults Tuesday and today two of them can hardly walk and are very lethargic, only opening eyes briefly. At one point one of them was shivering. They are in a brooder under the heat lamp. I got a little pedialyte into them, but they don't look good. They were fine yesterday. I have them separated from the third one who seems to be ok right now. There's poop in the brooder but I don't see anything different or obvoius. Any ideas? Just checked on poults, poop is white and runny. Got a little more pedialyte into them. Noticed one shiver again after he took a drink.
