I have a cria who is now 9 days old. He is quite a character. He was quick to stand, nurse, and run. He seems bright and loves to chase chickens. He makes vocalizations that I have never heard from a cria. It sounds more like a human infant crying than a cria when he's upset. He also puts EVERYTHING in his mouth... the fence, tree bark, dirt, feed bowls, etc etc. He gained 3 lbs. his first 24 hours of life and 2 more the next day. Anything I should be concerned about?
