We have a colony for our rabbits (3 does and a buck) and then a giant chicken tractor. When we were free ranging, the 2 month old chicks never come out or stay close to the coop (probably all the hawks!) Well, our male rabbit was out and he ran right into the coop and was checking out the chicks (He is a holland lop and weighs about 3 pounds). The chicks were not sure about him and he was super interested in them.
their run gets too dirty to quick for me to want our pedigreed show rabbits to live in there, but if they were just pets maybe.
