As a first time chicken owner, it can be very overwhelming to figure out which products are best for your girls health and happiness. The herb supplement got a lot of great reviews so we decided to try it. The girls feathers are beautiful and their vents are clean and they flock to this stuff. We will continue to use this throughout their lifetime. They are only 10 weeks old, but we look forward to super healthy eggs once they start laying. Lula, Red, Ginger, Alice, Hedwig and Chris Christie thank you for making such a great product!
