I have 6 Leghorn chickens, beautiful birds, but I noticed some were more, should I say aggressive/Friendly as in they come right up to you, but just don't touch...lol while others seem to stay at a distance. They are about 7-8 months old and only producing about 6 eggs per day, between all six. I feed them nothing but organic foods and add dried mealworms to their diet at every feeding. I am wondering if the more aggressive ones are hindering the others from laying eggs, I have 2 coops with nesting boxes in each. most times they choose one coop to lay all 6, once in a blue moon they will use both, but still only 6 eggs total. I have decided to add and 6 section nesting area, each 16 x 16. In hopes, this will get the others to lay eggs. I am hoping more nesting boxes will reduce the domination of the more dominate birds, so the others will produce eggs. I am also increasing the amount of water available. I currently have a 2 gallon water feeder, but really get nasty after a day and seems to loose water quickly. I had a water troth, but that got nasty really quick. I also heard that I should dry out and crush the egg shells and spread them around the pen to increase calcium intake, is this true??? Any advice would be great.
