You would have to have the chicken friendly plants outside the run. Anything you attempt to grow in the run will be destroyed within a day.My thought was to make it a sort of small garden-like space, so grow chicken friendly plants in part of it and leave part of it as dirt. Apologies for my ignorance- what do you mean by “refresh the soil”? What is needed?
The soil will eventually build up with too much poop load and will need to be changed as it will not be in contact with the earth.
Also I was thinking of 3 bantams, would that be ok?
It depends on the bantams.
