Milly and Molly look lovely girls. I am sure you will get some nice kids from them.
oops, did not mean to put you off ......but have you ever smelt a billy goat!!!
Nanny goats come into season from around September to Spring. I usually aim to get mine in kid around December, for a May kidding, mainly due to the long winters we have, and weather should be better in May. Once you have seen your goat in season for a few times, you can usually see when the right time to go to the billy is - no use going too soon in the season, or too late. I have had goats for 35 years, so am usually spot on with observations, and can take her to the billy and he will serve her straight away.
Stud owner will probably put your nanny in a pen next to the billy to start with, get them acquainted, then bring him out. He will snff her a few times, and then no messing. Its all done very quick, and blink and you will miss it. Can be a bit frightening if you have a first time nanny, but don't worry, the billy owner will know what they are doing. I would advise you to wear protective clothing for the occasion, including gloves, as the nanny will obviously smell after her visit, and so will you and your vehicle. Watch the nanny three weeks later for any signs of return to season, i.e. bleating, tail wagging, and again three weeks later, as sometimes they can slip the kid then. No sign, then congratulations, you have kids on the way!!
oh yes, billy kids can be difficult to find homes for, although castrated ones fare better than entire because of the smell. But, they can only ever be pets, so a lot of people do not want them, and I do know some people have their male kids disposed of at birth because they are of no use to them.
