First, make absolutely sure to get your hets from a trustworthy source! The only thing that would suck worse than not hitting the odds, would be to not hit the odds because your hets aren't hets!

It certainly does happen that the odds don't work in your favor. My only clutch of bps this season was a pastel to a normal. I got 1 pastel and 3 normal babies. I didn't strike out, but I didn't hit the odds. I also didn't do so hot on clutches overall. I bred six females, and only got one clutch. (Although one has been showing some signs here recently!)
