Hi, we have 6 hens and love getting fresh eggs every day,even my 18 month old ds gets on with them ok, they tolerate him chasing them around the garden. You could make a hen house and run with some timber and chicken wire, or look locally for a shed maker / garden centres often sell them too. As for the hens do you have a town nearby that has a cattle market, they often have hens and ducks for auction really cheaply.The only thing you'd have to bear in mind is they can scratch the ground and make a bit of a mess, so you wouldnt want to keep them right by your door,or near your vegtable patch and they can attract rats, so we keep our hen house well away from our house, although being free range, the little darlings always come and play in the garden during the day.
