I need help! My cockatiel has 3 more eggs to hatch. One hatched 2 days ago. I just clean the cage and added wood chips as they had none. They had previously but they took it out little by little. But, I noticed an egg that may be DIS. It looks grayish with a wet stain. Should I remove it or will the parents do it themselves? I didn’t want it to infect the others if it’s DIS. What should I do?
