As a small time goat owner, I get catalogs from time to time with sheep/goat related products.
The one I got this week showed some different colored spray that the critters get tagged with to them them apart; and had pictures as to how long the spray will remain visible through rain and just plain ol' wallerin' around that the animals do.
I also learned something new.
There is a colored pad that can be attached to your rams chest/brisket area that will transfer the color to the females back as mating occurs.
This way the rancher can tell which ewe is impregnated by which ram.
Good for keeping accurate lineage records.

Not sure what your discussion of mating goats and mating sheep has to do with this thread in the Religion forum.
However, the link you posted to the blocked site beforeitsnews.com, which also included a photo of sheep in the act of mating, is inappropriate for the Religion forum and it is also inappropriate for anywhere on Free Republic, even if you found the mating sheep on a site other than the blocked site beforeitsnews.com.
beforeitsnews.com is not welcome on Free Republic.
Thanks.
