So I am in the process of building a rack for mice and ASFs and can't find the info I want. I had originally built two food hoppers but on most racks people seem to use a top feeding method instead. My concern about top feeding is the 1/2 wire cloth and my mice escaping if the food gets a little low. What would you recommend and why? My initial thoughts are to use a top feeder area for the ASFs with 1/2 inch cloth and the rest of the screen be 1/4 inch, and for the mice make it all 1/4 inch and use the food hoppers, but I still would like to hear about which is preferred.
