I am keeping ducks and chickens. The duck feed is Purina flock raiser which is a crumble. The chicken feed.....
....I was using an all flock but recently switched to a layer feed for a few reasons....
The all flock I could get was Nutrena. I was not happy with the level of powder in the feed. I also have 4 birds that are higher producers and were/are having shell issues even while going through a high volume of oyster shell.
The layer feed I am using now is also Nutrena but is pellets. In just a month I have seen improvement in the shell quality even if it is not 100% better yet.
