I have a 10 week old cockerel who was limping, so I brought him inside to a dog crate 4 days ago. He hops around....has good balance when he's standing so I am hoping it won't be a Marek's case? This is the first time anything like this has happened... A tree limb fell outside the coop and caused a huge kerfuffle...maybe in the rush he was injured? I can find no marks or lumps...the leg is not hot and he doesn't seem to react when I examine the leg. How long do I let him try to recuperate in the house? Should I cull? This isn't a great life if he doesn't recover...I have 4 cockerels in my flock and will only need one. This one is the lowest of the pecking order in the cockerel group. I saw nobody harassing him though.
