My 8 month old hen, Lucy, started laying 5-7 eggs a week about a month and a half ago or so. About 4 days ago I noticed she did not come out of the coop when I opened the door, she had spent the night in the nesting box and stayed there. I went to work and she was still there when I got home. I took her out, no egg, and she drank, ate a little and went right back in. So...now 4 days later she is still doing the same thing. No eggs but acting broody so...I took her to my chicken friend who did not seem to feel there was a egg stuck in there and told me to lock her out of the coop during the day and see if that helps. She hasn't eaten much the last 4 days. Is this normal? Why would she go broody and stop producing eggs? I kind of thought the opposite would happen, she would lay and want to actually sit on the eggs....that is why I am confused and wondering if she could be eggbound. When she is out, she walks just fine which is a good sign, right?
