With all the Brood X cicadas emerging, my chickens have been chowing down on them. However, as of late, they have stopped eating cicadas (and are eating much less feed) and their egg yolks are very pale yellow. Could this be from too much protein from eating a lot of cicadas, and if so, how can I help their digestive systems get back on track? We are putting ACV in their water and giving them much lighter foods (veggies, etc)
