Hello I have a flock of about 26 bourbon red poults, used to be 30. They are 4 different hatches all within a month of each other. They turkeys that are mainly affected are the older ones. At one moment one seems perfectly normal then the next it is light and lethargic and eventually die. We just moved them to a new area with straw and they just started dying.
This started happening around 3 days ago. Two died today.
What do you think is wrong, how can I fix it?
