This band, consisting of one stallion and four mares, was photographed on the Virginia Range 06/15/18. Stallion on the right, no youngsters present.
Closer inspection revealed two mares with welts on their right flanks.
Bruises from getting kicked? Doubt it.
Insect bites? Possibly.
Handiwork of the PZP zealots? Who knows.
There were other bands with foals, why not these guys?
