Rosey is Camden's Mom. Bubbly and Jackie are also from the same breeder. I'm not sure how they might be related.

I used to have 5 Yorkies and now I have 3
 

I used to have 5 Yorkie's but now I have 3, whether it's 1 or 10 Yorkies or any other Breed. It's still the same concept, make them follow YOU! First of all don't walk them on a re-tractable Leash b/c you have NO real control over them! My Pack's made up of a Family - Father, Mother and their Daughter and they definitely act like it, so that might have something to do with it?
I walk them twice a day, early in the morning and late in the evening for 30 min. They walk on and off-Leash depending on where we are going, like the Dog Park or our local Lake/Park or around my Neighborhood. When I was Training my puppy Pom Pom, I had her attached w/a Coupler to Abigail her Mother, you have to make sure that your lead/Alpha Dog is well Trained and follows you, that way the rest of them follow you too! Your Leashes should'nt
be longer than 4 feet long otherwise your just giving them more Leash to tangle up among themselves. They also cannot be in an excited state of mind
before you leave your House or they will stay in that same state of mind during your walk. Hope this helps? It can be done as long as your calm and don't get frustrated or show any signs of impatience b/c they pick up on your
Energy.

Ummm, I have 4....and a 65 lb mix.......and a 45 lb mix.......I don't know how I manage! haha I have couplers for the little guys (2 on a leash), but I have to keep my arms way out to my sides so they don't tangle each other. I'm lucky I have a huge fenced backyard so I really don't have to walk my guys often. When I do go for MY walks, I just take whoever gets their butt out the door first. lol
