what does "butt-headed"mean?
Work was light and Jody spent long hours with Flag. The fawn was growing fast. His legs were long and spindling. Jody discovered one day that his light spots, the emblem of deer infancy, had disappeared. He ex-amined the smooth hard head at once for signs of horns. Penny saw him at it and was obliged to laugh at him.
"You shore expect wonders, boy. He'll be butt-headed 'til summer. He'll not have no horns 'til he's a yearlin'. Then they'll be leetle ol' spiky ones."Jody knew a content that filled him with a warm and lazy wonder. Even Oliver Hutto's desertion and the Forresters' withdrawal were dis-tant ills that scarcely concerned him. Almost every day he took his gun and shot-bag and went to the woods with Flag. The black-jack oaks were no longer red but a rich brown. There was frost every morning. It made the scrub glitter like a forest full of Christmas trees. It reminded him that Christmas was not far away.Q2: what does "lazy wonder"mean?

Filled with wonder / filled with a lazy wonder. filled with a warm and lazy wonder. The person feels inspired, awed by what they see. But in a very relaxed manner, where they can just enjoy it and not feel the need to become involved or engaged with it.
