The good news: Summer-goat is probably not pregnant. She's just "in good shape finally" now that Crystal and Goldie aren't beating up on her all of the time.
The not-so-good news: Penny-goat is pregnant, and it's probably twins. She's also *way* skinny, so she's going on a special extra-food diet starting tomorrow. Since she's a month behind everyone else, she's going to have to be treated with extra care (and maybe a separate field) when the other moms are dealing with their new kids and brooking no opposition or competition. ETA: The reason Penny was pulled off of the breeding list was that she is only a yearling, and is at the bottom of the pecking order, along with #15 and the two kids. With her kids a month behind everyone else's, she's going to be generally harassed while she is still dealing with being a new mother, and her kids will be pushed around a lot by the bigger kids.
Interestingly, the vet was concerned by the relatively high temperatures of the baby goats until he checked the adults. Everyone he checked was running between 103.5 and 104.1 degrees F. In any other breed of goat, 103.5 is considered "of concern" and 104.1 would be labeled as definitely ill. (ETA: that's according to him. As you can see from the 1st comment, there is differing opinion on this.)
