I have a barred rock who is about to turn one year old, and she has yet to lay any eggs. She has, however, squatted down when I went to pick her up and sat in the nest box several times for maybe an hour each time. Sometimes she even tries to get into the nest box with the other laying hen, effectively shoving her out and taking her place and pushing the egg under herself. She's not broody. Probably does this a few times a month. Her comb, face, and wattles are bright red and grown. Her pelvic bones are wider than two fingers. I just don't understand it. Her butt area is significantly larger than the RIR, like a tennis ball. If you ran a hand down her underside, you would feel a large bulbous fluffy butt. She seems perfectly healthy though and there's no visible redness or swelling. I am 100% positive she hasn't laid. No debate there. What could be the problem?
