Does anyone know what the colour should be of FBT poop??

Horrid question I know , but I have managed to spot my female FBT pooping the last three times, and managed to 'collect' it in a turkey baster.

I was curious to see what I could find in it, but when I squashed it on kitchen roll it's always blood coloured, with bits of hopper remains in it.

This has worried me - but is it normal to be blood coloured??

She's eating ok, is active & looks fine.
