They are like children, they have to be entertained or they fight.
They like high places.
They like new toys.
I have put some totes in the pen and the older guineas like to climb on them. I cut a hole for the smaller guineas to go in and hide. Guineas don't like dark places or low places.
I have put some poles in so they can roost on the logs.
Putting things in the guinea pen is hard work for old women. My hen that hatched the keets has started laying so I put her in hen pen again. The other hens have been picking on her.
