...had these types of discussions for years also....2002 ...with Brian Barczyck even in Daytona....briefly.....
eggs that are too full...too fat....swelled to the point they have added pressure inside...can and will deform or kill the kids.......might help....
different boodlines mixed
non-kinked line morph male
het females from 3 lines
drier eggs
check temps of females and eggs....
and now I guess check the rodent food supply....
(I fed my rodents corn ,oats, Zeigler lab block, dog food, and all kinds of other stuff for treats)...
I have seen kinks ...and some years seem to be worse (water theory)....
the only 2 super black pastels I ever made went from egg to freezer in 5 minutes....same line, deep dark ,good line....kinked badly)...
