I have a hen that I have suspected is moving eggs from other nest boxes to her 'preferred' one' but couldn't catch her. Well, the girls production is down, and I thought it might be because of her "attitude" (CRANKY!!) so I put some fake eggs under her. Hubby "collected them , so I marked them with a highlighter....and today I found 2 of them in the nest box NEXT to the one I put them in last night! Has anyone else had this happen, and how the heck does she DO it??
