Building my coop.

Think in these terms. You need four square feet of open floor space per large fowl on the chances you might have to keep them up for some reason. Since you're already planning on adding more then figure in for those additions now.

And take into account the human that needs to maintain that coop. Look at how difficult will it be to clean, collect eggs, fill waterers and feeders. You might want to plan on electric for the ability to have lights to work. I also had water to my big coop. But it had multiple pens with multiple waterers. It made it a lot easier to clean and refill waterers.

Thank you I just wanted to be sure I made it big enough. And as far as the watering goes I plan on using a rain barrel with PVC watering dishes. Should I include a watering dish inside the coop? And exactly where should I put the feed? Inside the coop or outside in the run? Because I have seen both.

It depends where you live. You dont need a waterer nor feeder inside the coop, unless you live in the frozen north like Minnesota during the winter. It's best to locate both of them in the pen, preferably a covered pen. You dont want rain water to get the feed wet and chickens dont particularly like getting wet neither.

I live in northeast Florida and we get sideways rains during thunderstorms and it can be a challenge keeping feed dry even in a covered pen. That's where tarps are your friend. It's easy to drop tarp(s) on the windward side of a pen to prevent driving sideways rains from getting the feeders wet. Bungee cords hold the tarps down on the chicken wire during the wind and rain.
After the storm passes, simply roll them up and secure them with a couple of bungee cords attached to the chicken wire, easy peasy.

My feeders and waterers were always in the coops. More for the convenience and not having to worry about the feed getting wet or the water turning green.

I tried feeders and waterers in coops a long time ago. The chickens made a mess of it inside the coops, creating more work. They can make all the messes they want in the pens, easier to clean and scoop up messes including poop.
I've never had algae issues in the waterers. I change them out every 3rd or 4th day and clean them as needed. I currently use plastic water containers and clean them out every 3rd day whether they need it or not.
I'll be switching back to the 3 gallon waterers in about 4 or 5 weeks hopefully.

With chickens, keeping everything as dry as possible is key.

A 6X8 run is not going to be large enough for 6 chickens. Convention says there should be at least 10 square feet per chicken in the run. IMO, even that is not enough and especially if the chickens are going to be confined in the run. A 4X8 coop is not going to be large enough for 6 chickens especially when you consider the floor space taken up by 3 nest boxes. I would go bigger in both aspects of your design and there would be no food or water in the coop.

Ken is really serious about his birds having large runs. He's right. That's where they're going to spend the majority of their day so bigger is really better.

It's April. Better get a hustle on. Those brooder peeps will be fully feathered before you know it. I'm just messing with you. But they will be ready for their new digs way before you realize.

What are you using for the roof? It looks like gutters with its high profile. I've never seen anything like it.

The rest is really looking good.

It's old siding metal that I picked up for free. I am actually going to bury a piece in the ground to keep anything from tunneling in. Any ideas on how deep I should go?

As far as my chicks go they are ready to come over now from across the street. I am hoping to be done by the end of the week with the whole setup.

Mine is down two feet. But I've got some really easy dirt to dig. A foot should be enough.

So you've seen them. How much time have you spent across the road just watching them?

You can lay an apron of 1/2 hardware cloth about 12-15 inches in width on the ground all the way around the outside perimeter of your pen. You can tie it in with the chicken wire or staple it to the posts on the ground. Grass will eventually grow the hardware cloth. Nothing can get through it. It beats digging and burying metal or fencing.
Besides, you're going to need that metal panel to block cold winds blowing in the pens during the winter or hard sideways rains during the rest of the year.

Yes I have seen them but they are in their garage and between my schedule and their schedule I haven't been able to spend time with them yet.

Thanks for that info that is good to know and is a great idea

It really looks good. And secure. How much longer before the peeps cross the road?

I was hoping today but I have a bit more to do. I am hoping by Wednesday.
