About 2 months ago I ordered food from amazon, for my chicks and they sent me the wrong feed. They said I couldn’t return, but gave me a refund. I’ve had these bags of food just sitting here, because it wasn’t the right food for my chicks. Question, is it safe to mix in once my chicks are 16 weeks old or is it best to give away to someone that has meat birds? My birds are not meat birds.
