So my hen stormy has gone broody from what i can tell. I went to close down the coop last night and found her in the favorite nest box all fluffed up around an egg. She did let me take the egg but today she was pretty hesitant. We don’t have a rooster so i need to continue to gather our eggs. How long will this last? I am kind of tempted to put some fertilized eggs under her to see what happens. If i do about how many would be logical?
