I mix a big batch of Black Oil Sunflower seeds, Animal Grade Brewers Yeast great source of protein, Henny Penny Millet, and Meal Worms, they love it! And it helps raise their protein levels fairly fast. After I have fed all of that (makes about a month I feed it to my girls in the morning once a day) I mix equal portions of their omega egg pellets, scratch, and feed corn (the larger than scratch kernels), a tub of quaker dry oats, and black oil sunflower seeds, in a large 5 gallon bucket cover it with water and three big glugs of MOTHER WITH BRAG (you can find it at the grocery store in the vinegar section its vinegar with amino acids) stir that around and I cover it with a dish towel and let it sit for 3 days. Most of the water gets sucked up by the mixture I give it another big stir and dish up for the girls it ends up the consitancy of oatmeal kinda mush like. I feed them this just in the morning and give regular omega egg pellets in my daily feeders for all the time eating and scratch in late afternoon in the free range area to encourage scratching around. This is very good for their digestion and they love it! I try and keep enough water in the bucket to keep about 1/2 of water on top of the mixture left in the bucket. You dont have to do all of these ingredients you might just pick adding the animal grade brewers yeast to their scratch or Black oil sunflower seeds are easy and very affordable. If you have any questions just ask I know I spoil my chickens but I have beautiful chickens with awesome deep orange yolks yum! Good luck it really will help to kick up their protein as all their energy is going into building new feathers the boost in protein will kick egg production too.
