Yes, if your pens are small and you go in each day and feed them treats, walk around, etc, your deer can be very calm. All mine are extremely calm but are not bottle fed. I sold a couple does and the buyer said it was like they were born at his place because they were so calm. The two doe that I have that were bottle fed nearly knock me down trying to get treats out of my pocket. The non-bottle feds just walk up and let me toss it on the ground next to them. However, none are fence crashers or every really run for that matter. Also, if you spend time within the first few days, I think that makes a big difference as they can almost imprint on you. My breeder, Lake Effect, is my tamest deer and he was not bottle fed but I did bring him in the house a couple hours after he was born for about an hour or two because it was cold and rainy and I wanted to warm his body temp. back up. In short, you can have a calm herd without bottle feeding but it's not likely that they will stick their nose in your pockets for treats but I would classify that as tame rather than calm.
