About a week ago one of my black silkie hens went broody (surprise surprise) and has not come off her eggs since. My roosters are only 18 weeks old this week, and I thought that there was no way her eggs were fertile, so today for the first time she left her nestand walked outside the coop, I picked the eggs up, thinking they were not fertile, but just to check I lightly shook one, behold my surprise when it is evident there is a chick in there. To be sure I picked up another, same thing, another chick. My question is 1) is it normal for the hen to leave the nest for a few minutes sometimes, and 2) did I mess them up bypicking them up? Will she return to them? Thanks!
