Always. You'd think they would have a sticky at the top of each section by now, detailing why you suddenly have an "egg eater", respiratory issues, laying decrease, losing feathers, decrease/increase in food consumption, increased predation, broodies or not having any broodies, increased smell in the coop, increased dampness in the run, increased algae growth in the water, etc. All these seasonal things spark more threads each year.....I guess that's why BYC doesn't just have stickies for them, as more hits equals more money.
