Ok as some of you know I'm moving my flock Tuesday night. It was next to impossible for me to purchase enough crates/kennels to move them all. So I have resorted to large boxes with extra holes for airflow. This will be a 2.5 hour trip for them. So my question is what would be an ideal size for my ducks? I'd like to split up males and females. So will be 3 runner males and 1 runner female and a Pekin female and mallard female. I don't want them to be cramped in so they get too hot but don't wanna to be able move around too much in there. The large boxes are 24 in by 18 in and 18 inches tall. Not sure on exact size of ex. Large boxes as I had to go to different store to get em, but they are bigger. I'm just not sure appropriate number of birds to put in the boxes. I would like to at least put 2 together so they aren't stressed more by being alone. Any input would be greatly appreciated. Also, I'm moving chickens too so if anyone here has input on that too please throw it out there for me.
