I usually guess the sex, keep a record using the picts of the day old kits. It's more like fun to see if I can get good at it. Every week I turn them over and check. But since I am using them for meat, I don't name them. I've lost a 4 week old kit, a 13 week old kit, a 6 week old kit and just culled two Thursday. These kits here don't get names or tatts until they are 4-6 mos, and I sell them or plan to keep them.
here's my guess, two males and a female. I can't really see what I want to see on the last pict.
