You're right Jac, Brian made it, so I suppose I wasn't really being fair, but I do think these poultry houses that you can buy are rather overpriced, when they are just a shed with extra bits!!!! lol
The little opening is the pophole that the chooks use to go in and out. so the big door stays shut all day, unless its hot in the summer, then we leave both open. Brian built that shed 4 years ago, and its never been re-treated, could do with it now I know, but that's not bad. In the big chook house, the chickens run on deep litter, which is only cleaned out every 6 months! or at the change of chooks The small one I've done once in the month since we had the POL's (Point Of Lays) This photo was taken when I had a couple of chooks in it which had been bullied, but its now home to the POL's which we got a month ago. Whenever we get rid of a batch of chooks, the houses are cleaned out, washed and usually sprayed with Jeyes, but since I had the chicks, I tried out Vanodine which we got from the feed shop. Its brilliant. It's iodine based, but was recommended by the editor of Smallholder magazine. Its £7.55 a litre, but 4 little capfuls is enough in a 10 litre bucket and it cleans as well as disinfects, and you can keep the bucketful until either the water gets dirty, or the iodine colour fades, then you make up a fresh batch. They say its so safe, you can even put a little in their drinking water to kill off any bugs, but I haven't done that yet!
And yes, the box on the side contains 3 nest boxes. You need a least 1 nest box per 5 hens, but we try to give them more so they don't have to queue!!!
You mentioned converting your shed into half shed half hen house. How big is the shed? They reckon 1 hen needs at least 2sq ft of space, so for 10 you'd need 20sq ft. If your shed is say 8x6 and you had half for chooks, that'd be enough. But have the run as big as you can, I hate seeing chickens squashed into tiny runs where they can't try out their wings! We are lucky where we are, as in the 5 years we've been here, we've never seen a fox and we are surrounded by fields.
That's probably why we've never seen a fox, they are all in the towns eating from dustbins!!!!!
