New to chickens a few question about construction

[knox_legend]

Hello to everyone this site. I have already learned a great deal lurking for the last few months and now I have my chicks in the brooder. I have 2 Dominiques 2 Sussex and 2 Silkies. I would like to have a coop that is semi moveable and portable. I understand with 6 chickens this may not be too feasible. I am planning on making the coop part 5x5 due to the amount and pre cut sizes of free wood I have and about 4 feet tall or so and about 12 inches off the ground. I was wondering if this would be a good size and what a good size for the run may be?

I would like it to be moveable if I have to move it around. I have decent size lawn tractor to move it so I'm not too concerned with weight. I would appreciate any suggestions or comments.

Thanks
