Some details on the “Auto chicken swing door weight and pulley system”
Note my system has changed and is different from the video, I no longer use any weights underneath the water buckets; the water pails/buckets have been changed from 3 litres to 5 litres. Transfer weight is heavy enought that I do not need to fiddle with added weights, stones and etc.

There are other items I had and did not count as expenditure in this project such as different sized nylon cable ties, grass trimmer line.
Grass trimmer Line 2mm: I used “constrictor knot” to make a loop on its’ ends.
Water tubes – need to straighten these out; google on how… by boiling in water
[Door half way open]
The door doesn’t fully open because the “working height” in the chicken sleep area is 50cm, the water containers can move up down ~50cm+. To fully open I will need around 1 meter of working height for the counter weight and water container to move in the coop.
[Open & Close length of time]
For my system it takes slightly over 1.5 minutes to transfer the 5kg of water across.
To close it is quick, but to open it takes slightly longer, close or open action need only schedule once in a day; use to be I had to schedule to repeat same pump action number of times in case the open or close action fails. Now it just works, pump life should drastically improve!
[Weight and pulley system]
1. transfer weight needs to be heavy enough e.g. 5 litres/kgs or more
2. Need to minimise all forms of friction if possible
e.g. take care on how each pulley is facing,
each hook is screw in and turn to just the right angle to minimise any forms of friction.
Just by changing things like these slightly may reduce enough friction to make a troublesome auto door to a working one!
