When my family finally decided to get chickens this past spring, I did a TON of research on how to raise them organically. We wanted organic, soy free eggs, so I read every book on raising chickens, researched the best organic feeds, and read every book/article/journal I could get my hands about chicken health.Probiotics are one of the most important supplements you can give to your chickens to keep them healthy without medicated feed! In fact, Purdue has commissioned TONS of research on raising antibiotic free chickens. While it is technically geared towards large commercial flocks, which I do not have and I’m against factory farming, the information is invaluable to smaller flocks of free-range, spoiled, and well-loved hens like ours!After doing all my reading and researching, I found that Probios is generally considered one of the best dispersible probiotics available. It is highly researched and is SQF Level 3 certified. That means that the manufacturing facility go through ANNUAL recertification audits and continues to meet the highest standards of food and supplement safety standards, both government and industry. So you can be assured you are receiving a quality and potent product.The 240 gram jar is perfect for those with small flocks or a family that includes multiple dogs/cats/other pets. We have 12 chickens and a jar lasts us approx 2 months. The powder can either be sprinkled on food or dispersed in drinking water. We personally add it to their drinking water to be certain they each get a good dose every day. When added to water, it dissolves easily with a little agitation. I use the shower sprayer on our hose and that works perfectly!While I can’t tell you exactly how much my girls are getting, what I can tell you is that I managed to raise 12 very healthy and happy hens. I started them on probiotics from day 1, and I did not lose a single chick. They are now almost 8 months old and we have had ZERO health issues to date. So I’m a very happy chicken mom! So happy, in fact, that I bought some for our cats and dogs as well!Overall, this is a great product that is extremely affordable. For fellow chicken moms, this will help keep your girls happy and healthy even on organic feed!Highly Recommended!
