Cabbage HAS changed the flavor to fishy eggs for my 3 hens. They can demolish a whole head in 48 hours and I was giving them two a week, so now my eggs are fishy tasting. I reached out to the pellet feed company thinking it was their organic corn free soy free pellet feed but aside from flaxseed nothing else in it would make the eggs taste fishy, so they asked me what else I fed my hens and only thing was a head of cabbage. They said stop the cabbage for a week or so and see how the eggs taste. They said brassica's will cause excessive Omega 3 production giving the fishy taste. They said their feed is a complete diet where the hens wouldn't need anything else. I put the cabbage in for their entertainment while Im at work. I'm waiting now for fish free eggs.
