I have searched about the risks of burying diseased chickens and have found nothing. I buried some diseased chicks in my backyard a year ago and since have lost about 6 older birds. I'm pretty positive that 3 of those deaths were not disease related, but my concern is that the pathogen is still around and those buried chicks bodies are causing harm to my flock. I buried the chicks approximately 2-3 feet deep and my flock does free range my whole yard including on the ground above these chicks. Im sure my girls do peck and scratch in that area. Is this bad? Do I dig them up? Any thoughts, suggestions, experience, or advice would be much obliged. Thank you all in advance.
