Love them without falling in love with them...that's a hard one!
You really from the start have to keep in mind what their purpose is and refrain from making pets of them. It's important to handle them and keep them tame, but socialize and save your bonding to other animals you intend to keep as pets. This is what my dog and rat are for.
I've got a bunch of new chicks and ducklings yesterday. I'm not planning on naming them because the layers will be going to freezer camp eventually. I treat caring for them as a chore to keep some detachment while I enjoy them. We can mutually enjoy each other's company for the time we have it before I have to act as a predator.
