You would have to work with race horses hands on to really appreciate this but here goes.Racehorse have sort of a sixth sense. Im not saying they are the smartest creatures but they are very tuned in to their surroundings. A "Nervous" type person can walk into a shedrow and walk up to a horse and the horse will try to kill them. The opposite effect "horse whisperer" type Monty Roberts can calmly communicate thru this sixth sense. Every trainer in the world will tell you that the key to a good horse performance is to keep them "happy". Happy involves good nutrition and Calm consistent surroundings.Sometimes goats are put in a stall or companion pony or rubber ball etc.Horses have very consistent routines and when their feed tub is taken away on race day, thats a break in routine and they know something is about to happen. Heres what is bound to happen with this detention barn deal especially with NERVOUS FILLIES. You are going to severly disrupt the routine. Horses do know their HOME STALL, why else do they go back to it when they are let out of a burning barn or when a horse gets loose on the track, they eventually go right back to their stall. So you take this Filly and place her in a stall that yesterday a strapping Stud Colt pissed all over the place. Dont tell me that these stalls will be completely mucked out and limed EVERY DAY. This Filly will sniff around and immediately her nervous system will be in overdrive.She knows she is not at home and ever horse in the shed row will have differing levels of 6th sense"ANXIETY" over this new surrounding and break in routine.24 hours worth of this could easily have a horse leave their race
"in the stall" My guess is you will see some really unexpected bad performances, especially with fillies. Im all for cleaning up the sport but these animals are a little more sensitive than most people give credit.Maybe lets just put the trainers and vets in a detention facility 24hrs prior

Just a thought
