Has anyone had experience running two bulls together in a herd; separating them with one bull in two different herds for six months; then bringing them back together in one herd? We are losing some rented pasture and will be putting some cows together to make one larger herd for spring calves and keep two separate herds for fall calves. Before I buy bulls raised together, I'd like to know what will happen if I separate them after one breeding season.
