I just saw him get both legs under him and he limped to the food, pecked twice then fell over and went to sleep, so the leg is working, just maybe injured.
It really does sound like it's an injury. Maybe just a pulled tendon, and it may heal just fine in time. Make sure that the baby keeps eating and drinking. Give some vitamen poly if you have some. Very little..very little. A tiny drop just a couple of times a day.
