I dunno to be honest - the dam came to me on loan (looked just like her, only adult!) as the owner had bought her from an auction but didn't have anywhere to put her, so as I needed a companion for my lad, the dam came to me. The new owner said she may be pregnant but didn't know, and the stally (according to the auction seller) was "just like her but a hand bigger". So out popped this little baby 8 months later!!
Bit of a sad story really
There's a couple more pics on my website if you're interested (link in my sig).
She was a cheeky little thing though, absolutely full of character!! Her and her dam were the first Appys I've met, and I do like them!!
