Turning a shed into a chicken house??

Welcome to the forum!
You'll only need one nest for three birds. You can usually do one nest per 4 birds. The only concern I see is, yes, the fox can't get in, but there are also hawks, racoons, etc. that can climb or fly into the run.
Chickens do much better in the cold than the heat, for the most part. If you get heavily feathered birds, like Cochins, they will be suited well for colder weather.
As far as the coop, you want ventilation but you don't want a draft, if that makes sense!

 

Hi Beedaisy. I've been working my brains on overtime thinking about how to build a cheap but warm/safe/ dry coop. So many things to consider. Lots of info on this site. Yer lucky to have a shedd. I think your idea of lining with plywood is a good one. I would do both the floor and the walls. But with the walls maybe just go up part way to help get rid of drafts but the gaps could still give you ventilation? Perhaps line with plywood up to 4 to 6 feet, depending on the height of your walls? From what I understand its not the cold so much as the moisture build up from the chickens. I'm not sure were Devon is located but I'm thinking its in the southern part of England, and that moisture and not cold would be more of a problem?? Read some of the post from folks in Canada were the coops have been insulated but not heated. I live in Michigan and got temp's down to -12 this winter so I'm very interested in their posts.
Also, are you sure about just three chickens? Good luck with that!!

 

Krisrose - is your coop insulated? I'm still in the process of building mine, and since I'm in Michigan too, I've been getting conflicting advice on whether or not to insulate...

 

There is nothing wrong with insulating a coop, as long as you still have ventilation. My coop is insulated in every part but the roof, and I have 3" ventilation holes (don't forget to cover them!) all around under the eaves.
My shed is wood also, and I have lined the entire inside with additional plywood. I've never had a critter try to chew its way in, but I did have a chipmunk that ran in one day and I couldn't get it out before I had to close the coop for the night. In one night, that little thing chewed through over three inches of plywood to escape! I was amazed!
Have fun with your new birds!

 

Country Gal- No coop yet!!! But I'v been reading posts all winter!! Got a major case of coop fever and I'm planning to go ahead and insulate when I build. I have also seen the conficting info on this subject. I think what helped me decided was the post from Shetland island. They insulated but did not heat. Ventilation is also very important due to the moisture released by the chickens during respiration, and an insulated coop with double walls won't have nearly as many drafts to release that moisture.
Maybe someone who has chickens in the frozen north will add their 2 cents about their coops?
I don't think cold would be a problem for beedaisy, I agree with lining the shedd with plywood not to insulate but for easier cleaning and to cut down on the drafts.

 

beedaisy, if you'll check the list of forums on the main page you'll see one called Here Am I, Where Are You. Read through there and find some folks who live on your island. There are several. You could post there and find out what they do.

 

I'll jump into this if Canada can qualify as the frozen North.

I would always insulate a coop. They stay cooler in the summer and warm in the winter.

You do want vents near the top on opposite sides you can open and close for ventilation.

If you are worried about the floor and cleaning. You can always buy a cheap piece of linoleum and glue it down. Many people around here have done that.

Rather than line with plywood. You can use coorugated pvc sheeting that is sold at most hardware stores. Cheaper than plywood and easy to wash. Comes in clear, white, red, blue, etc..

Just a few thoughts.

 

Kstaven- Good idea about the linoleum, I haven't seen PVC sheeting. I'll look next time I'm at Home Depot.
Yes, Canada and the northern states are what I consider the frozen north. Thats why I read the posts from these areas about coop design.
I don't take winter very well and it alsways gives me a warm and fuzzy feeling to see the nasty tem's in Canada!!
Sorry!!!
