My budgies are mating (1month now) but no eggs, why?

Question

Nesting box seems O.K.to them.

Answer 1

An egg is made when yolk is released from the ovary into the oviduct, where it will take 3 weeks or so for the body to form a hard shell around the egg and expel it. This hard egg shell takes a lot of calcium to form, and a cycling bird will need plenty of extra calcium in her diet to help her do this.  Is the female getting enough calcium?

Another possibility is egg binding.  Egg binding is when a bird produces an egg and cannot lay it. There can be various reasons for the occurrence of egg binding. Egg binding is very serious, and an avian vet must be consulted right away if you suspect your bird may be egg bound.
