My flock's favorite treats!

My chickens run to the fence as fast as they can when they see me carrying a box of these treats. Their eggs have been beautiful since they began laying again, and I'm going to start mixing this into their feed because they love it so much.

Shine-y Feathers!

Our hens love these treats, and they've already finished the box! Their feathers look slick and shiny. We will be keeping this on hand in the event of any feather damage from feather-pecking or molting in the future!

Egg-cellent Treats!

When we shake the box, our hens come running! We love the fact that these treats are made in the USA, the bag is resealable, and the quality of the eggs we're getting is top-notch.

My Hens Love It!

I sprinkled Defend on my raised beds so the hens could till the garden before spring planting. Our birds usually get a little bored during the winter due to the lack of vegetation, so these treats give them something to look forward to each day. Now, when I shake the box, they come running! I love being able to give them an extra immunity boost and get a tilled garden in the process, too.

Feather-Repair to the Rescue!

Several of our hens were picking on our silver laced Wyandotte, and she was missing lots of feathers around her neck. We began administering Shine, and within a couple of weeks, all her feathers had grown back and are now looking as beautiful as ever! I also love that the treat bag is resealable and easy to use.

SHINE is the perfect name!

My chickens look so much better after a week or so of giving them Shine. Their feathers look better and so glossy looking. I believe it in general makes them feel better. I love making my chickens happy. My chickens can't wait for their treats!

Great Boost

Enhance really helped give my chickens the boost they needed in laying eggs. I was thinking my chickens would go for the carrots (color) first in this formula, but the carrots are the last thing they pick up. Some people use treats to train, but my chickens ended up training me. As soon as my chickens see me, they start singing because they know I will go get their box of treats.

New Hens Have Calmed Down!

We added a small flock from a rural farm to our coop in town, and they were very skittish when they first arrived. Being in a new environment with the loud noise from town had them very stressed, and they were running around fluttering their wings and pecking at one another frequently. We started giving them Relax when they first arrived, and after 3-4 days, they really calmed down and stopped pecking at one another. Besides helping them de-stress, the treats have been a great way to bond with our new birds. Now, all we have to do is shake the bag, and they come running!

Defend review

I've got a flock of chickens and one duck, and I feel good giving my birds Defend to help their immune systems because they intermingle with my horses and always try to forage in their manure. I'll be incorporating these functional poultry treats into our daily routine!

Shine!

My chickens LOVE Shine. Every time I get the box out and sprinkle it on the ground, they come running, and I feel better knowing I'm giving them something to help with their feather health.

Enhanced is amazing!

We have a flock of 12 hens, and after they molted this fall, we were only getting 2-3 eggs per day. Within two days of giving them the Enhance poultry treats, we started getting 7-8 eggs per day!

Smells Amazing!

I got Sustain to help give my chickens some bone and joint support and make putting them in their coop a little easier. These are the best smelling poultry treats I've ever tried, and my chickens come running when I sprinkle it on the ground for them!

Happy Girls

We have a small flock of 6 layers, all appear to be happy and healthy. They made through the artic blast of Dec '22 and I'm sure 'Thrive' was a beneficial part of that!

Happy girls equals continuous eggs

The girls seem to be happy especially since they were in the coop for three straight days during our Arctic blast and there is no smell and low humidity in the coop. First application was probably two maybe three times what is normally used and have used it twice since in more normal amounts. Will continue to use through the winter months as the girls spend more time in the coop.
This is the third flock leader product I have purchased and used and will continue to purchase this product line.
