A fox are the wild duck in my yard and I saved her 10 eggs within minutes and made a homemade incubator and they’ve been striving. 1 1/2 weeks later, I candled them for the third time last night and they’re still going strong, but I hairline fractured an egg 5 minutes ago, dropped it when swapping a cooler egg with a warm one and it hairline cracked I’m so sad- it is not leaking or anything- so I found this “how to fix an egg” forum and signed up! Hoping for a miracle. These are my babies now.
