My feed store hens have always been healthy, I bought chicks there.
My old bird flock is (but may not stay that way) as they went and nosed around the paralyzed or semi-paralyzed rooster I had in a dog crate in the shed. He has some use of his legs and had kicked some food out.
I found him at the foot of a back wall of the run yesterday, when only 9 birds came out.
I hatched eggs - december had an incubator accident, 5 hatched, the rest did not, got too hot, of the 5, 4 were roos, but I had gotten more eggs from the same source and did a january hatch, got 7. When they were about 2 weeks old I bought 3 2 week old buff orpington chicks from the feed store. They still appear to be healthy.
I thought the first paralyzed roo had broken his spine fighting with the others, but a 2nd rooster has his right hip sitting high and his tail turning left today. The roosters were destined for freezer stock.
I have brought in 3 adult roosters a few years ago from the same lady I got the eggs from, 2 went to freezer camp, a neighbor's dog carried off the 3rd, no sign of injury.
If it is Mareks all my birds are in trouble, since my 3 year old hens went and gobbled spilled food from the sick one. I think I am going to take all the roosters for processing in the morning, as long as I won't infect anyone else's birds by doing so. Any way to clear a pen of the virus?
