Hello friends! I make my chickens a mash every night, my five pullets that are 34 weeks old have been getting Nutrena Hearty Hen that is made into a mash with water. My Bachelor Flock that is 38 weeks old and my mixed flock that is 20 and 21 weeks old get Purina Flock Raiser moistened with water. Every other day, or every few days, I stir in a really tiny pinch of Rooster Booster Vitamins & Electrolytes with Lacto Bacillus. I started doing it because we're having some wierd temperatures here in NC. Last week, I was worrying about frozen waterers and this week, some of my birds are panting a little bit (not a lot or enough to be concerned about, I truly believe it's the extreme change in weather, but I started the Rooster booster before this) and I am refilling waterers with cold water. I wanted to make sure it was OK to mix this in their mash. They have access to pellet feed anytime they want it, so the mash is really just to make sure everyone is full before lock up. Thank you for your time
