Why stalls can be bad for horses

So I am going to tell you guys why I am a no stall person and what I think about stalls

To start off, stalling is bad 90% of the time, that other 10% is in the case where you A. are in the stall with them because you are grooming or tacking up or something that doesn't take long   B. Your horse is injured and is on stall rest or C. You are at a show

I think horses shouldn't be in stalls at all, they really don't need it, if your taking care of them like you need to to they can easily be nice and happy outside 24/7, I dislike stalls, I dislike having Jet in a stall, and if you do have your horses in stalls you need to be home often clean out at least 3 times a day and feed at least 2-4 times a day. 

Now some side affects of stalling, if you guys comment on one of them I can go into greater detail for you :)

• Horses can't interact with eachother
• The horse doesn't have any mental stimulation
• they need exercise lots of exercise
• even if your stall has a small run, that is not enough space
• horses kept in stalls are more likely to get hurt during turn out
• some people say their horses exercise is riding, with 40 mins of riding 6 days a week your horse still won't get very much exercise, and why in the world do people think its okay to have their horses only come out to ride them?! The horse will only learn to hate and resent his job.
• So many bad vices that I can't even mention them, if the horses were out, they wouldn't be going insane bored, and chewing and cribbing, and they have these magical products that stop these vices that only make the horse owner look better because their horse doesn't do things that make it actually look like its bored.
• Did you guys know that cribbing horses actually are slower learners, or they don't learn hardly at all? If you want comment and I will post the article for you guys :)
• Can cause colic from many different reasons
• the horses lung health is put at risk with being stalled, they have no fresh air
• the stall smells like poop and urine, they can't get away from it, in pastures horses ususally pick a spot to poop and do it there away from where they eat
• constantly stepping in urine and poop can cause a wide range of hoof problems
• horses have respect issues, like I said horses teach first, horses also teach other horses, they teach pressure and release, so if your horse is never out with others he may have trouble understanding this

Some people say their horses love stalls, so if you really think this, if you left your stall door open, and your horse loves his stall so much he would stay in right? The answer is probably not, he would at most finish the food he had there "if any" and then leave to go somewhere where he wasn't bored out of his mind, theses are just some of the reasons you shouldn't stall your horse, and there are many more that I havn't mentioned! Thanks for reading and THINK LIKE A HORSE! :)
