Chicken Save !

Hey . So myself & Tracy are asking for a little help. We are wanting to rescue some hens from a battery farm the end of this month. However we have never owned chickens so we are starting from scratch and have so much to buy. We need to make a big of a run as possible. Fence posts are £20-£30 each alone . Bigger the run we have the more chickens we can give freedom too :) if anyone has any metal fencing or anything that would help we would appreciate that too. Thanks so much x
