How much land does a flock of 30 need to be honestly called pastured? We have ours on over 3/4 an acre. Half is wooded with lots of old layed mulch for scrathing and bugs and half is grassy yard planted with clover and millet ... rye in winter.. It was explained to me by a vet and a farmer that if I had more chickens,. or less land they could not, in all honesty, be called pastured chickens..I tend to agree and that's why we are keeping it at 30... what do you think and why? Thanks for your input.
