Can someone help? My girls (4 black jerseys) are about 8-9 months old. We had been getting 3 or 4 eggs a day. They had been eating their pellet food and when free ranging going after the neighbors bird feeder dropping (what ever was laying on the ground, mainly sunflower seeds). To keep them out of the neighbors yards ( 1 filed a complaint with the township) we started mixing Sunflower seeds into the pellets. Lately all they seem to eat is the sunflower seeds and the crushed oyster shells. We only get 1 or 2 eggs with very hard shells. A light inside the coop comes on around 5am. My DD open the coop door around 8am. No noticeable feather loss. We have tried pellets, crumbles and mash. Food and water is only currently available in the outdoor run. We are trying to think of some way to give them food and water inside but are worried about mice. Could all of this have to do with the weather getting colder and shorter days? Thanks to anyone who can give suggestions. This forum has help us alot this summer as we learn.
