My Black Australorp has gotten broody the last couple of years so this year, instead of trying to break her, I gave her some fertile eggs to sit on. At first, she was good with taking breaks. But now we’re on day 12 and she barely eats or drinks and has not had a bowel movement in 3 days. I tried feeding her on the nest but she barely eats that way. She’s too busy puffing up and clucking at me. So I take her off the nest and she might eat a few bites and drink a bit but then she gets back on the nest in no more than 5 minutes. She skipped one day of even getting off her nest. I’m afraid she’ll die by the time those chicks hatch. Is this cause for concern?
