When you bring new animals to your property its a good idea to have a small paddock ready where they can spend a few days before they join the rest of your animals. This allows them to get over the stress of transport and get used to a new home without being hassled by other animals. All herd or flock animals will fight at first to establish the "pecking order" (not sure what the cattle equivalent is! head-butting order?). If they meet over the fence and from a distance before they are put in the same paddock or pen, the fighting won't be as bad, because they've already got used to each other. The separation also gives you a chance to make sure that your new animal isn't sick with something that could be spread to the others. If you put them all together immediately you might not notice in time. Bratwurst and Frankfurter watch the other cattle from the safety of another paddock. This may be the plan, but as usual around here, it doesn't always ...
