So what makes em fall off?

good question. i have been shed hunting for 15 years and theres many different theories.#1 weather,#2 health #3 daylight hours
#4 new growth. I think it has alot to do with health and weather.the easier for an animal to access food in the winter means he will start growing new ones ,wich pushes the old ones off.ive always found that if an animal is sick looking or really thin or lots of snow and not much food,they will shed.giving them a better chance of survival.but on the flip side if we have a mild winter and they have lots of feed ,they should drop because the new ones are growing. thats just my thoughts whats every one else think?
