I have an aviary with lots of breeding boxes. One of my females has found a mate and started laying eggs. Today she was due to lay her third. I checked the nest box but only saw one - then I noticed that there were two on the floor of the aviary. One cracked and broken from the drop and the other in tact which I put back in the box. Why are the eggs being thrown out of the box? I noticed that there is another female in the aviary who has been showing a lot of interest in the same next box. She hasnt got a mate but she does go in and out of the next box when the laying hen is not in there. Could she be throwing the eggs out? I have now separated the laying hen and her mate into a breeding cage. She seems content in the nest box and hasnt left the eggs since I brought her in. Does anyone have any advice or tips for me please?
