I have a 2 year old filly that prefers to back herself up against a wall when resting/napping.
I noticed it a few months ago when we moved her into one of the larger “grown up” stalls, but she may have been doing it before and I just didn’t notice.
Because she otherwise seems normal, sound, and healthy I didn’t give it much thought. But I noticed today that she also does it when she is outside as well by using a tree instead of a wall. So of course the nagging worry fairies have started to mess with my conscious > I am hoping someone can tell me this is nothing to worry about so I can tell them to shut up.
