Re: Horse would not settle.
Might need something stronger than Valium.
I would geld them but they are all Group class.
The 4yo won The St Leger and The Derby in the first season.
The 6yo won a G2 and a G3 over 8f and 10f.
The 5yo is a G3 over 14.
Last season (my first) they had no temperament problems at all. The stayer had a blue triangle in a couple of races.
Now every horse in every race refuses to settle.
I introduced a couple of mares to the yard (otherwise all male) to see if that made a difference. It didn't.
Do the males all become more temperamental as they get older?
