I've been raising chickens for a long time, but first time duck owner. I have a Khaki Campbell who will be reaching egg laying age around mid September, give or take. I was wondering if ducks show any signs of getting ready to lay their first egg. In my experience with chickens, when they are going to lay for the first time, they will start to "squat" when you reach out to pet them. Just wondering if ducks have a tell-tale sign or not. Thanks!
