If you can sit near the brooder & let the chicks perch on you ... eventually take treats from you, they will ADORE you. Obviously, you do not want to manhandle them. (Or let kids smoosh them!) The hens that I brooded in my basement (2 yrs. ago) really see me as mama. They RUN to me (like ahhhhh!) when I am in the yard. A couple are super tame & fight for a seat on my lap. Not all of them are so bold. However, I would suggest that you handle each & every chicken. They need to be comfortable being handled. In an instance of an injury, you don't want to have to chase & net a bird. It is so much better if they will squat for you.
Don't be shy about enjoying them. Conversely, don't be guilty or weird if you cannot spend a ton of time with them. In the end, THEY have a flock & you are the *human*, the extra critter.
