If you;re able to fit a blue container in the crate, then your chances would be pretty good. New hay is fine, what counts is the overall similarity- same type of container, same color, same type of bedding. If the container doesn't fit, maybe cut it down if possible to fit in there? by the way I try to get cat litter boxes in the same color or similarly. (happens to be blue in my case) Makes it so much easier to handle the broody hens for sure. Hm, if the container does not fit in at all- maybe a blue covered cat litter box??
