Hi, i have been raising a duck for almost eight years now, and she is laying eggs.. usually about once every 24 hours. The past two days she hasnt laid any, and about an hour ago a really weird one came out. And i mean WEIRD. The outside is rough and sandpapery, and there a string like thing connecting it to a smaller, half developed "egg". It is about a 1/3 of the size of the normal eggs, and half of it is shell, and the other half is a film-like material, like it also hasnt developed yet.. i have never seen this before, what could it be?! And also, both parts of the egg have a thinner than normal shell. Any suggestions/ideas are welcome! Thanks!
