Geeez when will she foal? I have 2 mares due,I checked Windys milk Saturday morning,all 4 patches turned purple immediately.Tested the PH it was at about 6.8 so of course I got ready-watched her like a hawk Saturday,Saturday night,Sunday,Lastnight...still no foal! She waxed up Saturday around 6pm and continues to wax up and drip milk.Tested ph yesterday it was bright yellow putting it at 6!The lowest I have ever seen.She is very relaxed in the back end,butt rubbing,soft 'cowpatties' every sign of foaling...I called the vet,he says she will foal when she is ready.Im a nervous wreck about her losing all the milk she has been dripping.Anyone ever have a mare test 4 patches purple(calcium) and very low ph for days befor foaling?My other mares foaled within hours of these signs.
