it will dry up , i had a little bit of it here last year with my jill who was only feeding 1 kit & i noticed the teats that were a little red were ok a few days later when the kit used other teats, i have just read that reducing food & water intake slightly can help to dry it up as well, but its fairly warm here so i wouldnt risk limiting the water she has
Other than looking for a couple of kits for her to foster from a larger litter , is she the only jill you bred
