We are in the process of extending the chicken pen, which will eventually be about an acre in size ( 1/4 grass, 1/2 forest, and 1/4 bog which contains a seep). There is an oberabundance of insects, amphibians, and reptiles in this area, and the seep stays unfrozen for most of the year. I would like to know how many chickens I should put here, without risking damage to the bog/ seep area? I was hoping to put 40 on it, and supplement with feed twice per day. Does this sound like a feasible plan?
