Tommi will turn 21 next week. Although she shows no signs of cushings I am going to start testing her. I do not want this sweet mare to go through what my Chantilly had to endure. Tommi has been on 1 1/2 tsp of chasteberry for around a year. This is to help her cycles. Should I discontinue the chasteberry a few days before the testing. I do not want to throw it off. It is not absolutely necessary she get it. Karen,Tommi and Angel Tilly 3-2005 Bend, Or Happy Trails Tilly-Until We Meet Again
