My breeding pair of lovebirds have produced 3 clutches of eggs.. The first clutch produced one baby dead in shell, and the other three eggs were destroyed by the parents...The second clutch produced no babies, and the parents destroyed the eggs...The third clutch produced 6 eggs.. One hatched on Wednesday (2 days ago) and a beautiful chick was present....Within about 3 hours, it was dead, and there was blood in the nest. Yesterday, I noticed another egg had gone, so I gather they destroyed that one...This morning, there was another beautiful chick that had only just hatched, and off I went to work, hoping that all would be OK...I came home from work to find this this chick is also dead, and there has been extensive renovations of the nesting box.....There are three eggs left, and I think two might hatch, and I hold grave concerns about the wellbeing of these chicks....Am desperate for advice on what to do, and why the death of the chicks might have occurred.....PLEASE HELP.....
