It's only happened to me once recently - got some of the cheaper stuff from chewy, at the very beginning of Covid - I had to mix it with another feed, served as wet mash in the mornings. Took forever to achieve the right ratio, had to keep backing off the yucky stuff, adding more of the good stuff... I think I even added a little scratch there towards the end! But I did get a refund, so all's well that ends well, I suppose.I'm still interested with what people are doing with there feed that there chickens refuse to eat. Do you keep it till it's rancid? Do you compost it? Do you give it to someone? Do you try to return it to the store?
