Calculating due dates

Nigerian Dwarf goats cycle approximately every 21 days.  Jasmine was put in with a buck on March 6th, but it didn't take.  If in fact she was in heat at that time, then her next cycle would have occurred about the 27th of March.   However, the "clean-up" buck wasn't put in with the herd until the 4th of April, so she couldn't have been bred on the 27th.   Which only leaves the next heat cycle which would have been about the 19th of April, since the buck was pulled from herd on the 24th.  

The gestation period for Nigerian Goats is typically 145-150 days.  So armed withe this new information I am guessing that her due date will be between September 11-16th.   Which means there is hope for her udder yet!  It is filling, and her teat length is looking good, but it is definitely no where near as full as I would like it to be.  

So we have three weeks of seeing Braxton Hicks contractions and her doing "goat yoga" which according to some websites means she is trying to make room for multiples.   She is from a birth of quads, so its not out of the question, that she could be carrying quads herself.   (Twins and triplets are more common than singles for Nigerians.)   I haven't seen my other does do that much stretching so there may be some truth to it.   Time will tell....
