I wouldn't worry too much about the weaning process just yet, you have quite a few months to go before you need to decided exactly how to do it. If you wait until then to send Laney to stud (would love to see a pic of this appy stud too!!), wont that make for a really late foaling for Laney next year? Maybe we can work out an easy way for you to wean Tink when she is ready, and Laney can go off to stud early next year. I do agree with Diane that it doesn't hurt mares to carry foals one after another, but just concerned about the timing for you this time.
