when they loose their feathers and regrow new ones. They often do not lay while molting. To help speed the process you can add more protein to their diet.

Could be molt, could be the shortening daylight hours, could be both. Where are you located generally? How old are the birds? Lots of feathers laying around usually means molt, also you can examine them to see if there are pin feathers coming in which would also mean molt. If you are seeing a lot of yellow droppings it could be a sign of something, if it's only some it could just be normal cecal droppings which happen a few times a day, smell much worse than regular droppings, and color and consistency can vary. https://www.communitychickens.com/how-your-chickens-cecal-pouches-affect-its-droppings/
If you think it's something abnormal see if your vet will do a fecal test to check for internal parasites. (DE is not going to do anything for them, I would not use it).
