Is your bird or her mate tending to the eggs?

What temperature is the room at that she and her eggs are in?

yes; birds are tending to the eggs


temp. room 64-68 degrees


the clutch is 21 days and not hatched and the hen ia starting to lay again

is this normal ?


Expert:  Dr. Margo replied 7 years ago.



That temperature is a little low for a bird laying/brooding eggs.

You should have it 68-72F.

Also check your humidity. It should be neither too high or too low.

A very dry environment will cause the chick embryo to stick to the side of the shell.


Candling the eggs can give you a lot of information regarding whether the egg is fertile and viable (able to hatch).


Normally yes the eggs should have hatched close to this time.

It may be that she is trying to replace the last clutch that isn't going to hatch.


Make sure she has access to a cuttle bone to keep her mineral/calcium level up with this much egg laying.


I am going to include a link on how to candle the eggs. Viewing where they are in their development and where they may have stopped developing can provide you the information on what changes to make to help the clutch hatch normally.


You do not want your female exhausting herself trying to replace the unhatching eggs. Make sure she has access to a cuttle bone for calcium/mineral needs.


Please write back with your humidity information and what results you get from the candling.


The description of the candling is further down on the page.
