The chicks are getting BIG!

The chicks are getting big and are almost covered with their adult feathers.  

(Sorry for the red tone to the photo but their red heat light was in when I took their picture this morning.) They always seem to look like they have been through a wringer when their feathers are coming in with patches of down, patches of real feathers, and patches of skin showing under pin feather sprouts.  Poor things.  The coop we made for the original flock is not going to be big enough since we are doubling the amount of birds housed in it with the addition of the new hens.  We don't want to have any territory disputes or overcrowding so it's time for us to start deciding on a larger coop design and to start building it.  I would really like it if we could design it in such a way that it would allow us to keep their feed and scratch cans inside it, be big enough for us to walk inside it, and allow the girls lots of room to flap their wings.  We live across the highway from national forest so in order to keep raccoons and opossums out of the chicken feed we use large aluminum trash cans to hold it.  All bets are off if a bear tries to break into the cans.  I'm sure they can open the cans and I'm sure I will not get in their way.  It would absolutely be safer to have the cans in an enclosed building rather than on my back porch.  I recently saw a black bear along the side of the road on the way to drop my son off at school.  The bear had been hit by a truck.  The area we live in is known to be where they pass through occasionally.  Odd thing to see regardless.
