We have 5 layers, which I want to expand to 8, and I want to try raising a small batch of meat birds. Soooo... I am buying a 2 horse trailer to convert into a Mobil chicken coop that we can move around the pastures where the birds will free range. My current plans include surrounding it with electric poultry netting and installing an automatic pop door (Ador1) if I can get hubby to agree to those two purchases once he sees the price tags. My question is on the inside coop design to work for both layers and meaties. Roosts placed up high (at least higher than the nesting boxes) on one side and super low roosts on the other side (thinking a nice thick tree limb sitting on the floor) for meat birds to sleep on? When I say "sides" I just mean left and right sides of the trailer as I intend to remove the center divider that comes in 2 horse trailers. There would not actually be two separate coops inside the trailer. I figured they'd just co-mingle during the short time the meat birds are with us. Thoughts? Suggestions welcome.
