We have a male and female, they seemed fine, I don't know what happened?
Your zebra finch may have suffered from egg binding or a prolapse. They are common in zebra finches. Lack of calcium can lead to egg binding . A prolapse can be caused by laying too many eggs over a period of time. Another problem might be that the finches were too young to mate. Zebra finches should be about one year old before breeding, or health problems can occur. You also need to feed them a well-balanced diet, which includes fresh fruits and veggies, as well as calcium in the form of a cuttlebone, mineral block, or crushed egg shells from a hard-boiled egg. Don't let your finch couple breed again unless they are in top shape.
Your hen finch was possibly "egg bound" which means she couldn't eject the egg from her body. The normal reasons can be that the egg broke inside her before or during laying or it became too large to come out from the vent and the strain of attempting to eject it was too much. Sometimes the cock bird will attempt to mount her whilst she is egg laden and that can break the egg shells causing egg binding as well. I doubt if the cock bird will sit on the remaining eggs etc; it's not always normal for some breeds of bird to do this anyway. If you get another and the hen appears to be straining for a long time during egg laying it's possible the same problem could be recurring in the new bird. If you see this happening take the hen bird out of its' cage and prepare an eye dropper filled with baby oil or similar and then up end the bird and drip a few drops of the oil into the vent area as this sometimes allows the bird to pass the egg and continue with the hatching process.
pets question and answers,www.5d2d.com Always supply plenty of shell grit, greens or cuttle bone or similar especially before mating time, I've also found if you boil a chook egg and mix a part of it with a crushed plain unsweetened arrowroot biscuit before and after when they're feeding any chicks, that helps as well in the breeding and rearing of the young chicks.This is also ideal for other breeds including canaries and budgies etc as well.
maybe she strained herself to much when she was laying the eggs and it was to much for her little bird body to take. hopefully the dad bird will sit on the eggs now seeing as the mothers gone and you'll have some baby zebra finches!
