I have 3 hens. 2 KC's and 1 Mallard. The mallard is 21 weeks the KC's are 22 weeks. They have yet to lay any eggs. Do you know when they will start laying? My chickens have started to lay and are in the same coop as the ducks during the night and in the morning when they lay so I thought that would encourage the ducks to lay but not yet.. Any ideas when they can start to lay and what I can do to motivate them?
