I think it would be a good idea too...i do know that he will nip and kick and put a fit when he first meets a new horse, because aneighbor's horse got out and we had it in our field and samson pitched a fit!
I would definitely run it by my parents first, but the first thing we have to do is to ask her aunt and hope she's not as insane as my friend says and she would let us keep Oreo there... I've spent a lot of time at her farm with her horse- she only has a couple of animals there. She herself said she had a ton of hay and no horses to feed it too..It would be crazy I think if she didnt let us because she is in my friends family... the field is right beside her house, and it is HUGE- far larger than mine- and the only animals there are a horse and a donkey. She misses having multiple horses. She has a huge water source, and I think a horse would be more happy there... especially since my horse would be a bully to a smaller animal. I know that we have to be considerate of her though, she might have reasons if she doesnt want my friend to keep her horse there.
We know for sure that wherever the pony ends up she will still be a friend to my horse (dont worry he's a gelding!!) because if she's at the neighbors house we will still be taking her out on rides and stuff and she would probably be riding her to my house and keeping her at our house in our barn while she's here. If she's at my house, then my friend will most likey be at my house every day, which my parents might not be crazy about...
