Two weeks of waiting is nearly up... I have to hitch the horse float up tonight and get an hour of work off tomorrow afternoon, so I can get to the clinic for a 4.30pm appointment.
Fingers crossed! Indy has been super grumpy while out and about, frequently making faces and putting her ears back at Pav (who she is often incredibly friendly with) and Billy, and threatening to kick them if they get too close to her. I'm hoping the out-of-character behaviour is indicative of her being in foal.
