Is it possible to change how helmets can be applied on chickens?

The issue is the helmet piece gets quite stretched vertically.

Yes, it's a chicken with diving glasses and snorkel. :) The glasses are placed at the "beak" height. I think AWS considers the whole height "B" as chicken head, instead of height "A", which I suppose is the actual head.

The measure "A minus B" is, say, the chicken neck and the red dangling thing is its wattle.
