Hi there,although I helped my dad with his chickens, about 8 in quite a small back garden, that was 50 years ago, some things seem the same, but I guess much has changed! My Dad's garden was not big enough to allow total free range but they had a plenty big enough run and they were fed well, with plenty of opportunity to scratch and peck. We intend eventually having 9 Dorking Hens (just 2 at the moment) 1 Cockerel and 2 Dewlap Toulouse geese. (So we have 3 We are surrounded on 3 sides by a river and have sectioned off a part for the geese which they love.Will the best part of 3 wild acres be enough for all 12 (eventually) to graze and feed on or will we still need to supplement them? I have already bought organic laying pellets, as we have kept them in a smaller fenced off section where their coop is and we kept restricted until they got used to their new home, which they have now.I have been giving them some organic whole oats sometimes, and grit and ground egg shells mixed in with their pellets and some food quality DE. Will best part of 3 acres covered in long,long grass which has gone to seed, reeds and ferns,we get some slugs and snails, frogs, toads etc. What if anything extra should we give them?? These have already grounded themselves into their coop, plus their wings are clipped. The idea about letting out to graze and lowering their feed, or feeding them an hour or two before bed time sounds good. Do we need to do that.can chickens,or geese eat too much for their own good, or do they stop when full? Would they get enough grit and calcium just around the fields? They will also have access to very shallow, even in bad weather, streams here and there somay have no need to come back to their coop for water.
