She continued to sit on the nest all morning, so I decided to set up a separate pen in the coop, with food and water close by. When I moved her into the pen, I noticed that she had stolen an egg laid by my Lavender Ameraucana this morning and was sitting on it with the golf ball I have her last night. shortly after I put her in the brood pen, she left to go socialize with her flock mates. At first, I thought she wasn't committed after all, however, about 5 to 10 minutes later, she got all puffy as she headed towards the coop. I reintroduced her to the nest in the broody pen. Once she saw the clutch of 5 eggs I set out for her, she immediately climbed in and tucked them under her. Then she screamed at me to get out.
Thanks for all the advice. I don't know what will happen, but look forward to the experience, regardless of the results. I'll keep y'all posted.
