What hardness am I looking for?Great! If you only get a little I would check color and then ph. Sticky can be helpful but it can change right before or days before. Ph is usually a much better indicator. In fact they say that 90% of mares foal within 24 hrs after testing 6.4. Hardness can be helpful but it varies more. Usually you dilute the hardness but it requires a lot of milk. So you can just test it and see what it is but know it shows higher than it actually is. However it does show the normal jump.
