I had a 2nd sumatra start to go broody she was on day 3 of not leaving the box. I gave her some eggs today and BAM off the nest and no more growling. She even let me pet her, something I rarely attempt with most of my chickens. But she was looking at me just right and I thought why not. I have to say the solid black eye of the sumatra hen is something. It can be quite intimidating when they are broody but somehow quite a nice loving eye too. I left the eggs out there for tonight to see if she will go back to them.
