This original design (see notes) is an automatic self populating chicken farm with feather, raw chicken, and egg collection. I used a heavily modified version of my exponential chicken spawner to build this farm. The farm will automatically create more and more chickens until they are culled and collected. Culling the chickens does NOT kill off of them, so some remain to lay more eggs. It has the following features

- Automatic Egg collection
- Automatic Chicken spawning with collected eggs
- Automatic Feather/Raw Chicken collection and sorting with indicator lights
- Optional Egg Collection bin with indicator lights (Instead of using them for spawning)
- Easy Chicken kill switch
- Manual Egg feed (To manually spawn chickens)
- Chicken viewing area
- Feed override button to remove foreign objects from system.

2.4 Update:
- Added chest to manual feed
- Added Egg drop signal
- Added hoppers to catch drops from bugged chickens
- Various bug fixes

3.0 Update
- See Logs

I tried to leave as much wiring as possible exposed so people can explore it and see how everything works.

This was built as a personal challenge to myself. I know it's not really reasonable within a survival game because of the extreme amount of materials required. If you put this on your server, please leave the credit sign intact.

Things I want to add:

- A simpler kill switch. I tried messing around with the redstone to make the culling a one button press system. I could not figure out how to do that.
- Possibly expand the chicken farm
- Have adjustable culling (I.E kill half, 1/4, etc)
- Automatic Chicken cooking (Optional)

Additional Notes

Everything is original except the item sorter and the auto-furnace. I got them from here
