So buffy is a grey miniature pony and is 319 days gest and getting bigger by the day. She is due on the 10th feb going on 342 day gest
She is a maiden so it's really just a guess.
Sabrina is a shetland pony and is 313 days gest and really hasn't got much bigger over the last month.
She is due on the 16th of feb also going on 342 days gest.
They are both about 6 months along in the above pics .
