DH started our chicken tractor in March. It is based off one of the Fordham arcs, just more simplified. They are using the little shelf to jump up to the perches/nest just fine. I may replace the chicken wire with hardware cloth but right now they are in the main coop at night. And now that the chicks are too big for the brooder, Strawberry and Rosie live in their new home, helping make sure we have a good garden this summer! Thanks for looking!
