Ok this is the first year I have had yearlings and older mares and stallion and 3 month old babies Fillies I think are coming into heat so I know they have to stay away from the stallion is it safe to put them with the mares with foals at their side? or do they stay by themselfs. I have two yrl fillies thanks

Ok wasnt sure what to do with them. worry someone will get hurt. my one mare has been very mean to another mare not sure why as they have grown up together. might it be that shes bred and just mean now? I had to take her away from her as she was cornering her
