This is a columbian wyandotte cockerel, from a group I got out of McMurray hatchery from a June 3 hatch. Just over 9 weeks old. Isolated with the rest of the group in a brooder tractor, away from direct contact with our other chickens. It's currently a group of 12 cockerels in there, and I noticed last night that this one wasn't quite right. It was having a hard time getting around and was getting run over by the others occasionally. I initially thought it had injured it's right leg due to the way it was walking, so I brought it and a buddy out of the brooder tractor and into a chain-link dog kennel so it could rest/heal. This morning when I checked on them, the one in question just looks overall unsteady/wobbly and stumbles/falls over a bit. Everyone else in the group is normal still. I put the buddy back out with the group again (figuring they've all already been exposed if it's something contagious anyway) and moved the one in question to a more remote location to isolate him. I've read a lot about Mereck's disease, but haven't ever seen it. We've never had any Mereck's on the farm here, and have never vaccinated chicks. We have not acquired any older chickens, only chicks- day old to 3-4 weeks max, only a few of the 3-4 weekers. Aside from buying day old chicks and the few 3-4 week old chicks, we've previously hatched our own eggs. This bunch from McMurray has not been in contact with any of our other birds, except for what I could possibly transmit on clothing/boots/etc. These particular chicks will be butchered in a few months for the freezer, and I was hoping to put them out with the rest of my meat growers who will also be freezer bound in a short while. I'm hoping the videos will work... does this look like Mereck's? Should I euthanize him now? I can do a necropsy on him or take him to the local vet school for more detailed investigation. I know that if it IS Mereck's my flock is already exposed and I'll just have to deal with what comes down the pike, but am hoping that I can salvage the situation a bit... Please let me know any thoughts on how this boy looks. Thanks.
