Hi and welcome to BYC - you have some great feedback which i am sure you will have found very useful.
All the best
The other greeters have given you some good advice so I'll just throw one caution out...be careful buying pre-made coops. Many of them over-state the number of full grown chickens that will be comfortable in them, a lot of them are not well made and they can be as expensive as a coop you build yourself. Even non-handymen (and women) have been able to build their own coops and with recycled materials or by modifying pre-built sheds and they end up with great coops. Click on the Coops tab and take a look at all the different ways people have built them, there are some wonderful ideas in that section.
Thanks for joining us, I hope you and the kids have a great time with chickens!
