Honey is wearing a fly mask. She has severe allergies to the gnats and her eyes can swell shut. For that reason her pasture mate, Goldie, and she spend the day in the stalls and are turned out at night. With the fly mask and the nighttime turn out she is doing much better. She may have been bored or hungry. She is an eating machine and isn't happy with summer rations. I think she went looking for food in the other stalls that were vacated for the day. Goldie was in the stall next door so I don't think she was lonely. But since I am not a horsey psychologist I don't know. At least she didn't get into the feed room!
By the way, Her forelock is growing in so maybe she will have enough hair to keep the flies off next year. The forelock was just a "cotton ball" between her ears when we got her.
