I was going to basiclly ask this same question.So, Fred, even if the litter freezes, it counts towards your 60-90 days of "curing"?
I am using the deep litter method, with litter made mostly of leaves, with some pine shavings. I am thinking of removing just the litter under the roost for composting, since my leaves are collected in the fall, so I have some benefit to the garden this year.
I don't plant until the end of May so I can dump fresh chicken poo on the garden soil and even though it will be frozen solid for some time it still is "ageing" and as long as I stop adding it by the end of March it's safe?
I have a compost tumbler and have been adding the poo with kitchen scraps and it's all frozen and cannot be turned, it is also full now! so my plan was to just start dumping directly into the garden soil.
