Pros: Chickens like it & it seemed to give them more energy. Egg production picked up.
Cons: Stains plastic waterers
I bought some of this, this summer after a nasty infestation of lice. I thought my hens were looking a bit pale. Our temps were routinely in the high 90s and at times up to 107. I added it to their water 3 days a week for a few weeks. They liked the taste and egg production picked up quickly. I liked the results so I am still using it one day a week.
I use this product for any illness that pops up among my chickens. You can put it in water or on a piece of fruit or veggie or any treat really. You can only give it to your chickens for every day for a week or 2. I will try using it for molting this year. My 4 yr old australorp went through an awful molt last year.
