i bought a mini horse about a month ago from an auction. she was so sweet and nice. now she isnt so sweet. she kicks my 20 year old gelding .she kicks him everytime i feed them. my kids were washing her and found out she has alot of milk coming out. its not dripping but if u squeeze it, it shoots milk out alot. she is up to date on shots and dont want to call the vet out unless im sure...what do i do? how do i tell if she is pregnant? can u tell by pics?
