Newbie here. Arrived home around 6pm to find one my hens sitting in the nesting box. Did not come out when I shook their feeding can. Just checked on her, still sitting in the nesting box. Picked her up and placed her among her friends in the run. She went through a broody stage which ended a month ago. Checked her vent, noticed a yellow blob south of the vent. However, she laid an egg today, so not egg bound -right? Not to mention I found a pile with what I believe contains a tapeworm. One long worm with something akin to rice. Broody wormy hen? She was fine this morning. If tapeworm, any suggestions what to use? Treat the entire flock?
