Our gilt, who is now 101 days into her gestation, had a pretty pink posterior on Saturday which led us to believe she was 1 - 4 days before farrowing (according to a few sites we read). She is now NOT pink or showing any symptoms except her teats are filling out into nice small cones. Last night we pulled an almost finished shelter out into their pasture - just in case. (missing one roll bar) Tonight, she came running to greet me = obviously not nesting. Has this happened to anyone else?
