OK, so my mini I purchased on 04/21/2018, she is with foal and she is about 38" tall. How many days have ya'll had your mini's go? Minimum she can be is 328 days and maximum 341 days. I calculated if she came into heat around April 08 (reason being, the kill pen got her from auction and they had a stud in with them so I figure around 2 weeks max she was with a stud.) I've read mini's usually go around 320 days not the normal full size horse 335-360 days. Would love to hear your experiences The first image is yesterday 3/14 The second and third are from 3/10 !
