You maybe on to something. I know my broody's will run other ducks out of their space when they try to go in to lay an egg, but they always find another place inside one of the other houses to lay. Could be just taking a bit of time off too.My Runners are not laying - nothing for 6 weeks and just 1-2 a day for the last 2 weeks. I've got nine 2 yr old Runners, 1 is sitting on eggs, 3 have ducklings ranging from 4 to 8 wks old. That leaves 5 that are giving me, at best, 2 eggs a day. Noone is molting; everyone has fresh bedding and water daily,a small pond and 1 acre to free range on; the temps are perfect - 50s at night, 60s during the day. Do brooding hens and new Moms inhibit the others from laying? They have a 180 sqft secure house at night. There are squirrels around but I've never had a problem with predators. What am I doing wrong? Could there just be too many changes in the flock lately? I know they really don't like change - even something as minor as my husband letting them out in the morning instead of me unsettles them for a day or 2. Temperamental little quackers!
