I'm having bit of trouble this year with growing one perticular buckling. His momma was about 17" at the wethers, so I expected him to be small. He's a little underweight by a weight chart standard but he's a lot shorter. He was born in April and weighs about 38lbs. I feed him all alone now because I figured out he was a VERY VERY slow eater. He'll take a bite then look around and walk around then go back and eat and by the time he has two or three bites in all the food is gone. He's really pretty active, but I don't know if I'm overreacting.
