I made one of those chicken farms to see how well it would dump unwanted items. Essentially, I wanted to create an overflow safeguard for items that are in excessive amounts.
The first chest, located right after the copper chest, contains two rows of raw chicken, a few rows of feathers, and one row of eggs. i did the spread method where each slot has 1 items it in, so nothing will go in it but the item i want. The second chest is attached to a hopper and a dropper. The idea is that when there’s overflow, the system will place the excess items into the second chest, which then feeds into the dropper. A redstone lamp activates when the chest is open, sending the items into a lava pool.
However, it keeps putting chicken and feathers into the second chest even though there’s still room in the first one. I’ve noticed that raw chicken is ending up in two separate slots in the copper chest. I also added a third small chest that still has open slots for eggs, but the copper golem still sends items to the second chest and discards the eggs. Only occasionally does it send items to the third chest.

Could this be the reason of your problem? MC-300859 You can test it by checking if building it the other way around and checking if it’s solved
I’m fairly certain that this isn’t a bug. As I understand it, the Copper Golem doesn’t retain knowledge of which items are in chests it has previously checked, and it checks nearby chests in a random order. Thus, if it has access to the target chest and an empty chest, it has a 50% chest of finding the empty chest first and putting its items in there. The way around this would be to either have no empty chests, or to prevent the golem from reaching the empty chest until after it had already checked every other chest.
I forgot to add the image for the setup. The chest labeled 1 is the chest with all the items spread out. The one labeled 2 is the chest attached to the dropper system. As you can see, the pathing should have them going to the first chest and sorting the items, but it isn’t doing this.
