The feeding, watering and roosting area of your tractor must be under tarp shade.
Lost...?...from the tractor?
Put the tractor under the tree during hot sun time.
The reason that dirt/mud puddles ...vs container puddles...are more acceptable, they often get a worm coming up for air...not normally an attraction to water.
Even though chickens have a craw for grain processing..they love raw protein. Try meal worms and they go a little ballistic in wanting more.
Normally chickens do not like being in water. ...or having water on them...it scares them. Even rain creates a state of anxiety for most. It is a change in their environment and that is a typical
bird response to anything new around them.
We are reminded..they are not ducks.....or other water fowl.
Depending on the breed....plenty of shade and water will do. Movement of air in any form......fan...open window/door...breeze.... is a plus.
This is why breed selection is very important. Hot or cold.
We had heat index of 107 today with close hot sun.
