Some questions on Zebra Finch Eggs + their parents.?

okay first off I use bromme gr for rabbits for nesting matierials . yes she will lay eggs on the bottom of the cage if she has too .they will eat mixed vegetables and they must be chopped fine , a good finch seed mix, chopped egg shell (these must be put in microwave for 20 seconds to kill bacteria ) also feed egg food dry in a treat cup , egg food you can get in a pet store . also make sure they have a cuttle bone . I hope I helped and good luck .
