So one of our yearling ewes was supposed to be due "any day now" for the last two weeks! So besides driving me crazy, she has shown all the same symptoms consistently, swollen and pink back end, definitely has an udder that is not huge but developed and looks full. She has been in with a ram full time since December 16th, so with that date in mind, what's the latest I can expect her to go? We had May 12th as our first potential lambing date. Now we're waiting and waiting...and waiting.
