And look! It has grown wings! It must be close to maturing.
Young dragons are relatively defenseless. They are born with relatively soft scales, which are shed and replaced with harder ones as the hatchling matures. Once a hatchling’s wings grow in, it marks the beginning of maturation. At this point they are often capable of hunting on their own and are usually left alone by their mother.
Late Winter loves cold. He loves to romp about in snow, which is why he's called Late Winter. As odd as it is for a spring dragon to love winter, he is friendly, intelligent, and loves the chill that Snowy Hill has about him.
