Well, the A,D & E injection attempt on the difficult girl didn't go as well as the lambivac injection had done previously. Instead of just myself and my husband I had a few other helpers that day and it was too difficult to keep everything and everyone calm. We only managed to get 1ml into her and then I called a halt as she began to shake and bounce around and required the force of more than one person to hold her.
So I've decided to work with her 3+ times a week on my own for another 3 weeks before trying to inject her again. I'm being very patient and just standing with her in the pen, putting my arm out and doing some gentle TTouches and holds on her neck. No spitting at all today!
