My 22-week-old Khaki Campbells are the first ducks I've ever kept. There's been just one egg in the duck house each morning for about 2 weeks now. Either only one girl is laying or the others are taking turns. For the past few mornings I've been noticing some behavior from one of the girls that has me a bit concerned. When I let the ducks out of their house there is one girl that stays in there, looking to me like she's trying to lay an egg. She stands there sort of hunched up, neck bending & pulling her head in. Her bottom even seemed to have a loaded-diaper sort of shape to it. Today I let her stay in there for almost 20 minutes while the rest of her flock was eating/drinking/swimming in their pen. I finally pulled her out to take a look at her bottom. I've never tried to look at a duck's vent before, it's really hard to find amongst all those downy feathers! The duck was none too pleased either, but when I finally found it, it seemed to look "normal" to me. Small & puckered & dry, not swollen or red or discharging or hemmoroidal. So I didn't want to disturb her further by trying to go spelunking down her vent. I felt the flesh around it & didn't feel any swelling, could feel her little bones (hip? pubic?) on either side. After her exam she went back to her flockmates, eating/drinking/swimming as well as the rest of them. So what do you think? She's our blind duck the boys named "Aflac" and she's a popular favorite of the family. I don't want to worry or interfere unnecessarily, is this just normal pre-game warm-up for laying ducks? I just don't want to wait too long to intervene if she does have some obstruction. Thank you for your imput!
