I really wanted to separate her for a couple reasons. She isn't going to know the new place so I didn't want to put her in there too close to foaling because I wanted to give her the chance to feel comfortable being in a different place. She has never been without a companion so I thought maybe I could put her friend in and then pull her friend out when she is closer, I also wanted to get her off of the pasture as I am pretty sure there is some fescue in there. Fescue scares me as the last mare we purchased in foal was supposedly close to foaling had not seen a vet, was on fescue, and had placentitis gave birth to a premature, deceased, red bag filly (I realize all the other factors played a huge part, but my veterinarian said if they had taken the time to get her checked by a vet, taken her off the fescue, and treated the infection her foal could have been saved and had a chance. Unfortunately the baby was already deceased when we got her :( and the fescue she had was infected). I also will be starting her on all the extras via my vets advice and it would really be a pain having to separate her everyday to make sure she is the one getting the extras. The only other horse she likes is her buddy (the mare who lost her foal) so I thought pairing them together in the pen might help to ease her stress? (The pen is maybe a little less than half a football field) and it is connected to the pasture fence so she could touch base with everyone else if she wanted to.
