Bird eggs falling from broken nest. Can I fix or move it safely?

You can try to move the eggs if the nest is beyond repair, however do note that the eggs are EXTREMELY fragile, and are likely to break or crack even with gentle handling. If the nest is still viable enough that she is able to properly lay on the eggs without her or the eggs/hatchling being harmed, then not disturbing it, or disturbing it as little as possible is best.

If you are hoping to raise babies, then providing nesting material for the parents is best so that they can make a safe nest where the eggs are less likely to fall or break. The parents may also break eggs or discard them if they aren't viable or they are young parents that don't know what to do. Because the eggs need to be incubated, they need to remain in the nest with the parents in order to hatch. You can keep letting both parents try to raise a clutch (and be sure to provide a calcium supplement for the mother), or, if you don't wish to raise babies, can just remove and discard any laid eggs.

You can gently pick up the eggs if you need to move them or check them for fertility (small bird eggs will start out clearish and turn more opaque as they mature if fertile), however if you are planning on raising babies it is best to leave the eggs alone so that their parents can sit on them and incubate them without extra stress or accidental breakage from handling.

Thanks for reaching out about Nanu. Was the egg broken in the nest or did she lay it from a perch and fell? Sometimes birds know the egg is not fertile and will break it. Stress might also cause behavioral changes where they break/eat the egg. Maintain a good diet as laying lots of eggs is a huge calcium loss and they need to replenish. Good luck.

Leave them in the nest or nest box for a couple weeks, then remove one egg each week until they are gone. Removing them too soon or all at once may trigger more egg laying. You can also lower room temperature by a few degrees and limit her exposure to light. Shorten her days by using a cage cover in the early evening.

It may be that the egg was actually pushed out of the box as it is not viable. If they will not let you in the box (where there may be other eggs), or the egg is not viable, you can simply remove it. Otherwise, waiting until night when both birds are calmer and quiet may give you a chance to place the egg into the nest.

Removing the nest and current eggs won't replenish any currently lost calcium, but it may discourage Phoebe from laying more. If she doesn't have a mate, the eggs aren't viable and should be removed anyway. If you suspect she may lay more eggs, adding in a calcium supplement such as oyster shells or a cuttlebone (you can also use cooked eggfood, there are lots of recipes online) can help replenish calcium in addition to feeding her regular diet.
