I need opinions on how much living situations affect horse behavior. The back story is my daughter bought a 7 yr old tb in October . He was a lesson horse and very chill and doh dee doh in his personality. Moved him for a month to her trainer’s barn where he was the same way. Then we moved him to a barn with an indoor so she could ride all winter. First couple weeks same horse. Then she had a week where she couldn’t get out to ride for 4 days, they started feeding really green looking 4th cutting hay, hunting season started with people tramping in the woods and shooting near the pasture, and the leaves fell off the trees causing the highway sounds to get really loud , oh and the weather turned bad and they have been getting very intermittent turnout. all of a sudden he is a spooky mess and he started weaving.
This was in November. We have modified his diet which helped some, treated for ulcers which helped some and worked with her trainer about working through the spooks which helped some . But I am concerned that part if not most of the problem is the environment and how the barn is run. I am looking at places that are quieter and have more consistent turnout but I guess I would like to know about other people’s experience with horses behavior and different barns.
