Rooster temperment varies from individual to individual. One word of advice would be to not make a pet of him. Maintain boundaries between him and you. Making pets of the pullets is fine, but treat him like a "chicken."
You will end up with a nice flock of crossbred egg layers and meat birds. The ratio of 7 hens to 1 rooster may be a little low, but it all depends upon the rooster. If you notice that there is excessive wear and tear on your hens you can separate the rooster out until you want fertile eggs...
