I have quite a few different morphs and they really do vary by snake. Like my albinos, my older female and male are nice as can be, but my 2010 hatchling is nasty and was a picky eater out of the egg but now she kill anything but still nasty. My calico male use to be super nasty out of the egg and now hes calm as can be. My cinnys, pastels, yellow bellies, pinstirpe, hets and normals are great all around and have never had any type of issue with them. Now my granite girl is only a hatchling again and is super nasty but I think most of them grow out of it. As far as feeding issues go I've had a few go off but due to breeding. The only one that was an issue was my het albino girl went off feed for 7 months from the breeder I got her off of, and a month later after I got her she was and still is pounding down anything I throw in her cage. But I've heard about pieds being picky eaters. My pied male and het female will eat anything and my male is over 1000grams and my girl is 1100 grams. I'm sure you'll hear all different kinds of stories though
