15. Save the shells from your shell fish to give the chickens. You will have the best tasting eggs by the following day and the yolks will be almost red. Plus extra calcium. Quoted from Roda_Bruce 's Why I come out ahead post on 8-7-2010. Thank you Roda, I had no idea. I just finished boiling 5 pounds of shrimp. The 1st thing I did was to peel a couple (I ate them) cool the shells down under running cold water and yep, you guessed it---run to the coop with them. My 2 very spoiled Princess SLW hens greeted the goodie lady with bok boks and we got down to business. I shredded them up while they eyed me suspiciously, then I put the shells in a pan. The girls stalked the pan and finally took a bite. Then it was on! they gobbled them down. While I was boiling the shrimp, I boiled them over twice because I was also peeling cantalope and making frozen treats for the hens LOL. Throwing away shrimp hulls will be a big no-no from now on in this house. I will now add a cookie sheet of shrimp hulls in the freezer for future goodies for my girls. (Freezing on a cookie sheet then bagging in a zip-loc bag prevents a solid lump of glop) Now I have to figure out how many shrimp treats it takes to make the yolks turn red. I can't wait for them to lay tomorrow, we're gonna bust some eggs around here until I get the ratio of shrimp peelings to red yolks figured out!
