I dont know whats going on. In approx 2 days we have had 4 chickens die. Im freaking out. Our chickens are 9 weeks. Fully feathered. I noticed one was really sluggish yesterday morning. Got home yesterday and she was dead. Everyone else looked ok. Got up this morning, 2 more dead and one not moving very much at all. Got home from work today and she was dead and 4 more are actin sluggish, laying down, laying on thier side, barely moving, won't hold head up, eyes closed, move every know and then. I have isolated the 4 from the rest of the flock. They are in my kitchen now in a tote. What is going on???? What do I need to do???? PLEASE HELP!!!
