Health of the herd, bloodline. Then I take the kid and even in an infant you expect spring of rib. When running your hands from the top of their spine down the side of their body their ribs should move outward away from the body, not straight down, especially that last short rib. The ribs also should be flat, not like pencils. With my hand between her legs it should be roomy, in picking through several kids, the one with the most room, all things being equal wins. Teats with one hole in each one, perfect bite, perfect ears, and Nubian, alot more past the nose than the 1 inch or she won't have ears past her nose as an adult. Eyes far apart...width follows width and a doe with a good wide head will usually have a good wide body. Length of body...in Nubian thats slinky toy long in new kids. And always take your weigh tape. 2 months old 28 pounds, 3 months old 38 pounds no excuses unless on the paperwork it shows she was a triplet out of a 12 month old FF, or a quad or quint kid, than honestly maybe 5 pounds less, I would want the kids to me more anyway than those minimums.
No photos of the dams? No pedigrees? Nobody local to take with you? Vicki
