Hi, One of my ducks has been making a lot of noise in the last few days and acting a bit different. She looks to be in some discomfort and I was wondering if this could be due to the fact that she is about to start laying. Does this sound correct? Either she is in discomfort or she is just acting up. I would like to get a nesting box set up. Can anyone advise me on what I should do? I was thinking of just getting a basic wooden box and lining it with straw. Is this sufficient an how will they know to use it?
