I finally have Chickens!!!

I went to the NW Poultry Show IN Stevenson, WA today and picked up these little guys. They are Blue and Black Plymouth Rock Bantams. They are all 5-6 months old and the pullets have started laying (though I have not gotten an eggs yet). The cockerel has a rusty little crow that needs a lot of work They were hand raised but are reasonably nervous from coming to a stressful show to a new environment.

These are my first chickens and I am blown away by how gorgeous they are! I was seriously shaking from excitement on the drive home from the fair. This trio should produce 50% black and 50% blue.
I was prepared for chicks not full grown chickens so we had to run to Coastal for feed and pine shavings. I had to make a temporary roost (which they are not using ) They gobbled some food and had some water and nesting in the corners of the coop, again with the

I do have a few questions. We got them Purina Layer Pellets, is that a good quality food? This may sound dumb, but it's ok for a roo to eat layer, right? Also, what seems to be a chickens fav handout treat. I want to tame them down a little by giving them treat, but honestly I don't know what to give them.
How soon do eggs become fertilized? I think he is around 5-7 months.

Anyway, here are the new crew. Left to right, Vera, Violet, and Zebadiah (Zeb or Zebbie for short )

Here is their current digs. I can nearly stand up in it and I'm 5'9'' so it's pretty big. Lots of room for more chickies


-And that red thing under Zeb is a tomato that I attempted and failed to use to win them over

 

Thanks
Yeesh! Where do you keep them!
