a few questions regarding baby balls that have narrow heads - do they fail to thrive or do they typically eat and poop fine? has anyone bred a narrow-headed bp, intentionally, coincidentally, or accidentally?

i have a dinker female with a crazy wide-stripe harlequin pattern...and i've been having doubts as to whether she is genetic or possibly a fluke or incubation issue pattern. she laid 4 eggs for me and it wasn't until after she laid that i noticed her head seemed slimmer than my other females and her boyfriends. of course i am nervous about the eggs now. i got her from a reliable breeder who sold her to me because she doubted she was genetic. any thoughts/info appreciated.
