I am having a problem with cattle ( all cows, black angus ) that I look after killing koalas. I heard them all mooing today and went to see what the comotion was and unfortubately it was too late for the koala. Found anouther dead one a few mounths back and now think it was probably the cattle too. Anyone else have this problem ? I am thinking about removing the trees they are travelling too so they stay in the tree line, not sure how else to stop it happening ?
