I have one RIR about 2 1/2 - 3 years old. She seems to be setting in the nesting box a bit more then ususal and is all flattened out in the "broody position". However, she does get down during the day and goes outside foraging, etc. Last night when I got home, I had to dig under her for eggs. She was in a box with 3 that she had rounded up underneath her. Do you think she is practing or is she really broody? I've never had a broody hen before. I would totally be up to marking a few eggs to let her try out motherhood.
