I recently bought 13 Delaware pullets and 1 Speckled Sussex rooster. The pullets are about 4 1/2 to 5 months old, and the rooster about 4 months old. Since they came from the same source, I put them together, but separate from the rest of my flock. Everybody seems really healthy and active until yesterday. When I got home from work and went out to feed, I saw the rooster laying in a corner on his belly. There were some feathers missing from his rear, so I could tell he had been picked on all day while I was gone. I went over to him and stood him up. He could walk, but hobbled like his feet hurt. The first thing I thought of was Marek's! I pulled him out and took him into a heated shop and put him in a tote with water. Then I noticed his neck looked swollen. I thought about an impacted crop. I felt his neck and there was a long "knobby" tube feeling thing right in his throat area. I felt as I followed it down, and it seemed to go right into his breast area, but I couldn't feel a larger "bulb" like the crop at the bottom of it. Still thinking that could be what it was, I brought out a bowl of bread soaked in vegetable oil. He ate about half the bread and drank some water. This morning when I check him, he seemed a little better (a little more lively) but there was loose very green poop and a lot of it behind him. Back to thinking Marek's........ When I got home from work today, he had died. I just had to know if what I was feeling was his crop, but it just didn't seem like it. I cut his throat open from his chin to his breast bone. What I was feeling was his spine! It was right there in his throat area and arched like a banana. He didn't seem to hold his head funny at all, but it is a wonder. Could this be wry neck? Would it show up this late? Would it come on that fast? Has anybody ever heard of this? I am just dumb founded! Please shoot your thoughts at me! Oh....one more thing. So far everybody else seems just fine. God, please don't let the rest of them get sick!
