We are getting 2 Border Collie puppies and will be training them separately (we've read Ed's article) Should we put a screen between the two pups' pens to keep them from being too doggy?

We are getting 2 BC litter mates. I've read Ed's cautions on doing so. We are both experienced dog trainers/handlers and will be training the pups separately, one for each of us, etc. Question: We have outdoor pens for our present 3 BC's and also for the two pups (the latter on our patio under cover as the summer temps here are 100+ daily). Should we put a screen up between the two pups' pens which are next to each other to discourage them from becoming "doggy" or is that taking it too far in this respect and not necessarily as when they are out of the pens, they'll be interacting with each of us one-on-one and not each other?

Thanks.
