Were to start my chicks are 1yr old started laying on and off, now seems more off than on, july of this year they were putting out 5-8 eggs a day all has stopped since then and only got 4 eggs. I feed pellets, shells ,fresh water every day and no eggs. I clean there nest boxes every day because no matter what I put in there (shavings, shedded paper, straw, broom grass, ect.) they dig it out. I have not seen any snakes, racoons, fox, or eating of eggs by others.Please any help would be helpful.
