I stated using Nutrena Feather Fixer about a month ago. I read reviews but was a bit skeptical about this product working. My hens look great. Pin feathers started showing within just a few days. This doesn't stop the molting process but makes them recover their feathers faster. I have over 200 hens and won't feed any other food in the future. I like the size of the pellets and yes, their byproduct is less stinky. My egg shells are perfectly smooth and strong. I was buying great feed from a milling company and adding calcite for egg shell strength. My egg yolks are a rich deep yellow that my customers love. I will never go back to the other feed. I have about 1/2 percent feed waste, the hens clean up what is on the ground. If you want great looking hens and better egg shells listen to me and switch. I don't tell others her in Utah about the product because I want my eggs to be the only ones looking this great. It costs a very little more but the hens eat less because they are more satisfied nutritionally. In the end you save money. Do your hens a favor and go get them Feather Fixer.
