Last photo might be able to show her size. She's on the left (duh), Pants is in the middle (Pants is a damn small cow though), and a more normal sized cow (who is a year older than Chunk) is to the right.
I'll name any of Mel's calves names with an "el" in them. Mel's daughter last year got the name Shelby. If she has a bull calf in future he's getting the name Melvin.
You can see that her eyes are a bit of a light colour, similar to Mel's. That's unusual, cattle generally have eyes that are super dark unless you look up close. I don't think they'll stay that colour as she grows, but we'll see.
Two random things:
1 - Her nose is shaped a bit funny. It's like her nostrils are a bit bigger in proportion to the nose than they are in other cattle.
2 - She has a small white line in her eye ever since she got pinkeye last year. Visible in last photo. That's a bit unusual, usually if cattle keep a mark from that it's a small circle.
