Feed prices and sheds for henhouses?

Hi all,

I have been offered 10 hens because their currant keeper doesn't want them anymore. How much should i expect to pay to feed 10 chickens in a month? I originally only ever expected to have 3 hens so the 4'x4' henhouse i'm building will have to be sold and replaced with my spare shed. How do i make a shed into a comfortable henhouse for them, are there any special tricks of the trade?
If it makes any difference the chickens are fairly large and 2 years old (RIR i think but i'm not sure).
Also how many eggs should i expect from ten hens?

firstly your spare shed will be fine thats enough room for 10 birds , all u have to do is add a perch for them to roost on of a night and add a good clean deep bedding of straw or shavings. u can make your own nest boxes out of old wood which i have done or something even easier is if u have get a bit ply thats say   a foot high  u can use that to block of one end of the shed it will be dark behind there an the girls will love it . my shed is 8' 8 i think an i trianagled one corner of an my girls love it to bits .

u may be paying up to £15 a month for feed for 10 birds but that all depends on how much u feed per day , the only way u can work out your cost is to buy one bag an see how long it lasts for .i probably pay £44 a month to feed 17 birds , mine have layers pellets , mash, an corn but cost of feed is different for everyone .

Hi, we have six hens, mainly warrens, and I worked out that we spend about £10 a month on them.  This is for shavings, layers pellets and corn.  We give them a few handfuls of corn in the afternoon when we are about.  They all lay every day despite the warrens being ex-bat and apparently past their best.  They would be nearly two years old now.  They live in a shed conversion and are fine.  Good luck to you.
