So we're planning on getting some meat birds this summer to raise on our 4 acres. Hubby has this image in mind of free-ranging pastured chickens running around in a large paddock (either our 1/2 acre pig pasture or a moveable electric poultry netting situation). But from everything I've seen and read so far, everybody who does meat birds seems to use chicken tractors. Hubby keeps asking me why we need to do it that way rather than just have free-ranging pastured chickens with a coop they can be locked up in at night (my first guess was that building a coop would be harder work than building a tractor). Can someone explain to me why this isn't practical with meat birds? What are the advantages of having a tractor (that override the "cons" of having them limited in range and choice of forage)? And just how much of a coop do meat birds need, given that they won't be here for cold weather and won't be laying eggs (do they still need perches? some of the tractors I've seen just have a covered section). many thanks!
