kiwi and tweety are brother and sister (their mom and dad are not releated) when i found out they were male and female and not brothers as i was told when i got them, i separated them, they were really sad so i put them back together. i have had them for a couple years now.this morning i found an egg in the bottom of the cage, it was jamed in between the bottom tray and the cage, the egg broke and it looked like a regular egg with a yoke, does that mean it was fertile? what should i do, should i put the nest box on the she will not drop them to the bottom of the cage.
NEED ADVISE............
