Are your chickens going to free range or will they be kept in the triangle-shaped pen? I'm biased in my opinion about free ranging chickens if at all possible. It eliminates so many problems if you can let them out during the day. They take care of ticks and bugs in your yard, are happier and make better eggs in my opinion. Plus all the pecking problems are no longer an issue if they are not kept on top of each other, along with sicknesses that are spread from bird to bird if they are in close quarters. My husband is a professional woodworker, so we have plenty of wood shavings for bedding in our chicken coop.
We have a dozen chickens, including one rooster and they love running around in the yard, scratching and pecking for whatever the Lord provides. We started with 7, had them for a year and then added 5 more the following spring. We live out in the country on 6 acres, so we have plenty of space. We added 4 ducks to our collection last spring - the messiest creatures God ever made. 2 are male and 2 female - we thought we had 4 hens. Keeping them in the house until they are big enough and it's warm enough for them to go outside is unbelievably stinky and messy. They can turn a clean container of water into a mud hole with one touch of their bill. So far they all get along and walk around everywhere single file in a row. Very entertaining - talking to each other all the while. We use straw in our duck coop. Our duck hens lay eggs regularly and they are great for baking.
We lock our birds up every night at dark and let them out in the morning around 9am central time. We also have a border collie that watches out for them when we are not home.
Good luck with your new endeavor of raising chickens. You will learn alot and if you have any questions, someone has asked it on this website, so you can find an answer.
