Stressed hens and egg-laying hens can benefit from the addition of this high quality vitamin and mineral supplement in their diet. This palatable pellet may be especially beneficial for chickens living in Calcium deficient regions or those with a diet low in calcium.

This formula is also enriched with other key minerals and vitamins to support healthy nutritional levels, and is supplied in a convenient to use and accurate dosing paste.

How much should be fed per chicken on daily basis

Asked by: Kendall
Thank you for inquiring with Santa Cruz Animal Health. One scoop will dose 3-4 adult chickens.
Answered by: SCAH Rep
Date published: 2021-08-03

The instructions say "Feed one scoop twice daily scattered in coop" Is this per hen? Or is it for the whole flock? Obviously there would be a quantity difference depending on how many hens you have. Please clarify.

Asked by: KimberlyK
Hello! One scoop will supplement 3-4 birds.

We can’t separate the old girls who no longer lay from the layers. Will this supplement hurt the non-layers by giving them too much calcium? 

Asked by: LeeR
Hello! This supplement is safe to give non-laying hens.

Rated 5 out of 5 by from Great supplement for rich egg yolksAs a newbie chicken keeper I was on the lookout for food and supplements to improve the health of my flick as well as the quality of their eggs. I tried a number of feed and supplements before finding UltraCruz on Chewy.com. A few days after adding the Bone and Egg supplement to their feed I noticed the yolks were richer and firmer. Friends and family are always asking if there are any eggs to spare!

Rated 5 out of 5 by from Produces beautiful, healthy eggs!Thank you, Santa Cruz Animal Health! We live in northern Idaho and have 34 chickens. Our large family is used to 30 eggs per day. This past Fall our chickens went through molting, for the first time, and produced zero eggs for nearly three months. Around mid-December they started laying three to four eggs on a good day. Little to no eggs for many months simply does not work for our family, so we went looking for a solution. After just three weeks on the UltraCruz Poultry Bone and Egg Builder, we are elated our chickens are consistently laying 12 - 15 eggs per day now and increasing! We are pleased to report that even during the shortened days and negative winter temperatures here in Idaho, the quality and production of their eggs have drastically improved on this supplement. Peeling our eggs has never been easier. And not only are the eggs healthy and beautiful, but our chickens have never looked better! Thanks to UltraCruz for creating a wonderful product that will continue to be a constant in our chickens' daily diet.

Rated 5 out of 5 by from It's working!I'm just about done with the first 10 pound bag and I am definitely noticing a difference! Not as many broken eggs and the problems I had with a few hens laying thin shelled eggs is improving. I will be putting this on auto-ship!

Rated 5 out of 5 by from Strong ShellsThis is the best for making strong eggshells!! I was able to change thin fragile eggshells to hard thick ones in a matter of two weeks. Wow. Used every day. They love it.

Rated 5 out of 5 by from Stronger shells!!I started out with the 2lb containers but once I witnessed the quality of eggs and started going with the 10lb. I had a few girls laying some soft shell eggs and its been a few weeks since that. I check the quality daily and i am very happy with the results. I just made another big order yesterday. I recommend this to everyone i know that raises chickens. I have also tried multiple brands from the feed store and this is hands down the best in my book.

Rated 5 out of 5 by from Excellent supplement for overall chicken health.Usually don't use a lot of supplements, but thought I would give this a try. Been having issues with thin eggshells. This has helped tremendously and within a short couple of weeks.
