I don't know an awful lot about breeding BP's, and genetics has never been something I'm good at so it may be a silly question. But is it possible to have say a "runt" in a clutch of BP eggs? One that doesn't grow quite as big as usually expected...?

I got Pretzel when she was (supposedly) 4months old. Which would put her now at 19 months old. She's only just 2ft, and she just seems tiny. She eats well (weaner rats), she poos well, she sheds very well.
Munch is (supposedly) also 19 months. He's just over 3ft... So I'm not sure that they're the same age now. Pretzels deffffinitely grown since I got her and has bulked up, she used to fit in the palm of my and and now she doesn't.

Someone (a friend) suggested that perhaps, by some chance of fate, I picked a BP just like myself - except instead of being vertically challenged (me being 5ft), she's errr...Horizontally challenged
