guys enjoy this website and it is very informative. my question I have 6 hens and a rooster in a 10x20 old dog run can not let them free range due to neighbors. Is this enough space as I am looking at adding 2 layers. Out of the 6 hens only 2 are laying so i am getting concerned (got them end of march). I feed them laying crumbles and scrapes from the garden also put grass clipings in. advise please!!!!!
