Just got back from a road trip and realized I hadn't switched out Georgie Girl's 2 eggs for wooden ones. One was cold, but the other is completely opaque and warm. Is it a fully formed chick or is it rotted? I am very much against letting pets reproduce as there are so many homeless animals, but I can't break it open if the chick is so far developed. I am going to be vigilant about changing out eggs in the future!
