As it turns out, the timing is such that these Icelandics must have been bred to the Icelandic ram. There are a few later pregnancies, likely bred to Walter, the Cotswold. I suspect the Jacobs are two of those. It will be interesting to see what a Cotswold/Jacob cross is like. There are 3 lambs and two appear bred as well. They were in with the Icelandic ram, who is small, so hopefully they will have easy births.
The Icelandics and Merinos have begun to develop their udders. Heidi, the black and white Icelandic appears almost ready to birth, with the other Icelandics right behind her. Some sheep develop an udder up to 2 weeks before birthing, while others develop only when birth is imminent. At any rate, the ewes are definitely fat. It was hot today, 27, and they were waddling around panting and hiding in the shade. The excitement is about to begin!
