Getting Cattle Inside The Barn

I need to get Scarlett, Rosella and their calves to start coming into the barn so I can have the two moms artificially inseminated again and so I can tattoo and sell the calves. I began by tempting them close to the barn with bowls of grain:

I don't care if the other cows eat any grain, but I decided to give them some if they come close enough:

Rosella and Scarlett are both producing large amounts of milk, so they are always hungry and ravenously eat any grain or hay they find:

Rosella was the bravest and the first to begin coming into the barn, returning to her former regular stall:

Then Jasmine, Rosella and Amy began coming into the barn. That giant on the right is Amy. She was smaller than the others when she arrived six years ago, seemed a bit oddly shaped and was sometimes bullied by the bigger cows. Now she's a giant, albeit with a docile personality:

Because Rosella couldn't reach the bowl on the floor as easily as the other cows, I made a little stand for her bowl of grain:

 Winston, Scarlett, Ruby, Violet:

 Winston has resisted coming into the barn, but he's getting closer:
