Pygora Goat Fleece

Jack and Mackenzie both have beautiful fleeces that are nearing "harvesting". I am watching the two of them closely, since the fleece must be shorn just at the right time, since it WILL begin to felt on the hoof within a week or two of it being ready to sheer. The cold weather is an issue, since I don't want to shear too much off. They need to keep warm in this cold New England climate! If I can leave a good inch and a half or so on them, they will be warm and toasty. But, I run the risk of felting the fleece if I leave it on too long, in an attempt to grow it longer. Ideally, I would like at least a three inch staple on the shorn fleece. That means they need about a for or five inch staple growth...
