We got our first chickens about a month ago. 3 hens and a rooster. We'd been getting the eggs daily and we decided about two weeks ago that we allow them to fertilize and have some babies. Well, they've got 10 eggs in one nest box, and we check them a couple times a day, but the hens don't seem to ever be sitting on them. I think I've only seen one on them once or twice. The chickens are about 1 year to a year and a half old, so I don't think they're too young. Could it have anything to do with having so many eggs from different chickens in one nest box? I just read about the golf ball thing today so I'll definitely be trying that out to get them to use the other nest boxes. It's pretty warm here in Georgia, but I'm not sure how warm they need to be kept or how much the chickens need to sit on them to keep them viable. The eggs are somewhere around 12 days old, and I tried candling them, but I don't think my light was good enough. I'll have to build an actual candler. Any help would be appreciated.
