A few months ago I had a hawk or owl attack wipe out half my flock, so I have been putting them up at night and haven't lost anymore. I found their first eggs the day before tragedy struck. They have since been laying in there coop and I let them out in the morning. They WILL NOT go in the coop on their own. I would like to expand my flock in the future, so that's where my question comes in. If I let them out in the morning and they won't go back in the coop till I put them there how long can the eggs go without being sat on and still hatch them? I have 3 hens and 2 drakes, welsh harlequins. I was thinking about waiting till my chickens started laying and let them hatch my ducks. Should I not let one or more of the ducks out just to sit on the eggs? Will they be ok to go all day without being kept warm, I was doubting that option. Thanks for any advice. Also one drake seems to be picking on the other. He has some feathers kinda wearing out around his eyes and I have seen him pick as well. Anything I can do to stop it?
