My budgie egg is cracked but not hatching after 19 days. What's wrong?

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.

It would depend on if the eggs are fertilized or not. If you only have female budgies the eggs will not be fertilized and will not hatch. If you have a mating male with female I would recommend keeping the birds in a quiet location that is low stress. The female bird will care to the eggs and keep them warm. If you find she is leaving them in the open you. An put material in the cage so she can build a nest.

Yes, female birds can lay eggs without a male around but they will not be viable so should be removed. Males can mate with males, but if you suspect you have a male, and a female, and they've mated and laid eggs, then you probably have a pair (and at least one female). If the eggs haven't hatched in three weeks they are likely not viable and should be removed.

Thanks for reaching out about Blue. The average incubation length for budgies is 14-16 days, once she starts sitting on the eggs. A thermostat regulated heat lamp can be used to regulate the temperature. If she is going into and out of the nest box, and has laid egg in the box, she is probably comfortable with the size, as long as it is large enough to rear the young. Regarding nutrition, a wide variety of vegetables and a plant protein source (legumes) is important to replace nutrients lost in laying eggs. Good luck

The average time for gestation is about 21 days. If it has been 28 days, the eggs are either infertile or the time has been miscalculated. It would be best if she was not bred again until she is much older, at least 1 year old.

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.

It is not unusual for all eggs from a clutch to not hatch. However, if your budgie actually broke the egg in order to eat it, then it may develop that habit and never raise a clutch again - instead eating all her future eggs. The egg itself is not bad for her and will not hurt her, but it is an undesirable trait for her to eat her eggs. Thank you for using pet coach.
