When composting mortality having the right conditions will ensure a good result. Remember to start with a good base of carbon bearing materials in the bottom of the bin. Wet birds to help hasten the process and then cover completely to keep other animals out of the composter. Monitor composting using a composting thermometer in order to tell when compost needs further attention or to pull and spread. For best results compost at 45-50% moisture with temps over 110o F.
Be sure to have adequate materials at hand to compost, so to be at the ready for when its necessary to handle mortality on the farm.
