Zebra Finch egg laying
My female zebra finch lives with her male partner. She recently laid 4 eggs. 3 of them are fertile, I see heartbeats as I’m candling them. One of the eggs, I noticed was different from the beginning. It is the oy egg without a heartbeat and looked empty when I would candle it. I decided to take it out and break it. There is only a tiny bit of yolk on one side, and no other liquid was in there. It was just dry. Why would this happen? I feed her very well, all my birds are healthy and are given vegetables everyday and also have cups of sprouts in their cages to eat, they also have cuttlebones and are fed eggs 2 times a week. Is this just so eyhing that happens or is my bird not as healthy as I think she is?
