I need some help please. I have searched this board but find too many different answers to zero in on to know what to do. Currently my 8 week old chicks are in an old 100 gallon stock tank and we are rapidly trying to finish their coop since they are getting so large. They do have a small wire run that I put them in during the day. My problem is that I have one of those TSC standard plastic feeders (red bottom, white top). They scatter feed out of that something awful. I fear that once our coop with a slightly larger and more permanent run is finished, rats or mice will just love the fact that they scatter all this feed. Not to mention how expensive and wasteful. Please advise any help with a type of feeder they cant knock feed out of. Thank you so much.
