Thanks for the 'shape' reason they stop going into estrus. It is usually restricted to only a couple times around here, late Oct. and Nov., and of course, any calves conceived after the normal rutt, if born, won't survive the following winter, if they survive at all.
: The weather is all screwed up here as well. As is happening this year, we also had mild weather last year until March, then the temp dipped to -35. I expect much the same this spring. Cold with lots of snow, but late when things used to be melting. We had a green christmas this year, quite beyond normal. I remember some with -40 temps and 12' of snow on each side fo the driveway by the 25th of Dec., with my dirt-bike handlebar sticking out of a wall of snow.
: So far, we've maybe only 12" of snow on the ground, with temps running above freezing most days and freezing at night. The bush has a bit more, of course, which seems normal as the elevations rise each direction from the city, except south.
: Around here, that bull would be fortunate to have antlers so long - makes things more difficult for the wolves.
