I got no examples but I've herd of ball pythons getting egg bound yes it happens. This issue seems to be sketchy and heres what I make of it with all the stuff I've read, tho I have no personal experience.

When it comes down to it, can you breed a female small with no ill effects, yes. If a female isn't ready, she won't breed or eggs won't develope. theres been no proof or solid claims that small females have more of a chance of egg binding than a larger female but one trend has been notice.

say you breed a female at 1000 grams, and you get 4 eggs, not bad right, so next year shes now up to 2000 grams, she still gives you 4 eggs... eh so you try again next year and shes up to 2750 now and still you get 4 eggs.

the trend has been notice if they were bred small, they lay less eggs for the next coming years. the other fear is if you bred them small and they go off feed... well they don't got much weight to fall back on.
