I have a small flock - just three adorable silkies. I have been building their coop and run, and for the time, they are living in a wire rabbit cage, and getting "play time" in the yard, in a fenced in, covered temporary type run during the day (weather permitting). I have another silkie "on hold" at a farm about a half hour from my house. I know she needs to be quarantined, and I do have a second wire cage, but this one has a plastic floor, versus a plastic droppings tray. Does anyone have any recommendations as to what I should use as liner for the new girl's temporary cage?
