I went to my lot this morning for my morning chicken routine and I go to check the one hen I have setting and her nest is completely empty. All her eggs are gone, no shells or anything. I then look a few nests over and see her, dead. She has no bites or cuts or anything that I saw. She just looks like she dropped dead. Can anyone PLEASE tell me what could've done this? I am thinking a poisonous snake but I really hope not. I live in southeast USA and mostly around where I am it is black snakes which are not venomous but we have copperheads and the occasional rattlesnake as well. Any ideas are welcome and I thank you in advance. EDIT: Not sure if it makes a difference but the victim hen is a small bantam as are all my chickens.
