My finches laid eggs 2 weeks ago but aren't sitting on them. What now?

It's possible the eggs are not fertile which is why she has given up sitting on them, or they may be ready to hatch as two weeks from the last laid egg is about the right time for it. If she doesn't return to sitting on them you can use a bright light and hold up the eggs to them to see if you can see any development inside. if the eggs do hatch, having some baby bird food on hand to help assist with feeding is best as five babies is a lot for one mom to handle!

Baby birds are not usually born with feathers so that would be unlikely that you would see feathers within the egg, however viable eggs tend to start off clearish and then become more opaque as they age. You can also hold them up to a candle or light source (carefully as they are fragile) to see if there is anything inside. If they are not sitting on the eggs at all, the eggs may not be viable, the parents may be too young or inexperienced. You can attempt to incubate the eggs yourself if they are viable, however if they are not, simply removing them and ensuring your birds have adequate diets and a calcium supplement can help encourage them to lay more eggs.

Incubation in budgies is about 18 days from the day the hen begins sitting on The eggs. You are probably correct in saying the eggs are infertile. If there is no male present, they are definitely infertile. Wait until Coco loses interest, then remove and discard the eggs. This will prevent her from laying "replacement" eggs. Remove the nest box afterwards.

If she just laid it, you will not be able to determine fertility. Wait 5 days after she starts incubation. If you don't see a network or blood vessels, it is likely infertile. Wash your hands prior to touching the egg. Handle it only if you can't get a light source behind it.

The incubation time for eggs is about three weeks so if they had not hatched in that period they were likely not viable and it is possible the female kicked the eggs out of the nest. You can check the bottom of the cage to see if any egg pieces are there. Making sure both birds are on a balanced diet with calcium supplements for the female and enough natural sunlight can also help ensure healthy egg laying if you are looking to breed.

Birds will not usually sit on eggs until the entire clutch is laid. Clutch size varies by bird and by species and whether any eggs are lost or damage and need to be replaced. Eggs are laid most often about every 2 to 3 days (some daily to every other day).

It's possible, however it may be that your finches are nesting together to try and lay eggs/raise a family. They may also be cold depending on their location, and so are staying in the nest for more warmth. Making sure their cage is kept clean, they are not in a drafty or cold area, and that they have access to food and water can help. Checking the nest for any eggs can also alert you to if they are trying to raise a family. If you suspect they are ill, or they are showing symptoms such as completely listless behavior, not eating or drinking, diarrhea, vomiting, etc, then scheduling a vet visit to rule out any health issues is always best.
