Monica of At Wits End Homestead in Victor, Montana (a bit south of Missoula) talks about her deep bedding system for her chickens. Her chicken coop uses chopped up used christmas trees. She also talks about her experiments with deep bedding. Originally she used leaves and then she tried wood shavings/chips. But she found she was having to put down more every few days. With the chopped up christmas trees, she was adding more just once every month or so. Deep bedding is where you throw more bedding down all winter long without mucking out the coop. Then you muck out the coop once a year. She also shows off using buckets for nesting and how this helps with mite control. https://www.youtube.com/watch?v=zwjPj1p1Azo Please become my youtube friend!
