so, I got numerous replies from my questions regarding egg eating chickens: have two chickens that starting laying about a month ago, one Rhode Island Red and the other an Americauna. Got advice: black oil sunflower seeds, which I've tried, adding crushed oyster eggs, which I've tried. Two suggestions which I tried were to fill a store bought egg with Dawn dish detertergent after blowing out the egg and sealing with wax; the other with hot mustard and sealing the same. What I later realized is that chickens have no sense of smell or taste and that I was basically giving them a treat!!!! Thanks to those of you who do not realize these facts - and then the coop smelled of hot mustard and dawn dish detergent and the chickens had massive diarrihea. Just a suggestions for us newbies to chicken raising - if you don't know for sure of your advice, please don't give it - it really leads to a feeling of failure and mistrust in advice given to you by "experienced" keepers. I've kind of lost my faith in this advice. Any experts out there? Personally, I've found that taking the eaten shell and putting it in front of the "offender" and scolding with a loud "no" has worked the best. Honestly, I think they are bored. and don't know any better because they don't have a veteran layer to show them the ropes.
