I went to my nearby ethnic market today and bought some rabbit. I'm a frequent customer there. As I was leaving, the owner of the store asked me if I wanted 10# Swai Fillets 10# Pacific Red Snapper and 10# Cod Fillets for free!!! He said that they have been sitting in the back for a long time and that no one wanted to buy them. About 1 month. I didn't think this was a long time. Are these ok to feed?
