I am a chicken and duck owner. I cracked an egg this morning and found what looked like, at first, a blood clot. I realize from time to time that can happen, but this was a bit bigger than I have found in my chicken eggs so I investigated a bit further. Once I separated it from the egg, it looked like a worm. Can they have worms in their eggs? I haven't seen anything else to indicate that they have worms. Has anyone else had this happen?Thanks for any insights into this.
