Dear Members
My white albono red eyes (Love Bird) lays 4-5 eggs and just no or only one chick come out of egg. All other eggs are fertile but chicks die in the eggs and can not come out.

Is it due to weakness of any one of the parents? If yes please let me know what should i do.
If not then what is the problem and how it can be dealt with to come out of this problem.

Waiting for kind response and guidance.
