Not fearful, but you want your roosters to respect your space. The rooster should give you about 5 feet of room. They should not stare stink eye at you, they should not start excessively crowing and/or flapping their wings when you come in. Or puffing up to look big.
Roosters are not like puppies and kittens, which if you are nice to them, they will be nice to you. In chicken society, every time two birds meet, one is lower and one is higher. The lower bird moves out of the way. Sometimes, if you are moving out of a rooster's way, or if you are letting him sit in your lap, you are taking the lower position, it is not that he likes you, it is that he is not afraid of you.
Each rooster is a crap shoot, and some are darlings, and some are nightmares. Many times, people not used to chickens misread the cues and signs, and this forum is full of posts, where the darling becomes the nightmare in what seems like overnight.
Just be aware, what appears friendly, sometimes is not, and a rooster full of himself can give a pretty violent attack. Not all do, but often times, pets do.
