Some people use straw though it is not advised

, it must be checked on a daily basis and must be turned over completely. If straw is left untouched, the top appearance will look clean and fresh, while underneath it will sweat and create mould.

It does not take long for this to give off spores that soon affect the birds’ respiratory systems. This can have very serious consequences for their health. Straw can also makes an excellent haven for lice and mite.

If you have no option, and must use straw, always use a dry powder underneath and turn the bedding over ever few days, adding powder each time you do so.
My preference is wood chip or Hemp bed which is as is more absorbent and lasts longer, Chopped hemp is a natural, dust-free, quick to compost, sustainable, eco-friendly product. It has odour eating properties, is highly absorbent and has an added boost with Eucalyptus pellets added to the mix, offering a natural way of freshening up your hen house. Eucalyptus is well-known as a mild decongestant, which can also kill air-borne germs in winter. It is anti-bacterial, and research points to its anti-mite properties as well. Hemp Bedding absorbs up to 12 times more liquid than straw and four times more than shavings!
My local supplier sells me this in a large bagged bale for £8.40 whereas wood chip is £6.50 so there is a difference in cost's,but I know which one I prefer.
Also.How many hens are you having,what size of coop etc etc and I or many others can advise you on what size drinkers and feeders you shall need.Plus types of feed.
Hope this helps
