Ok. So, I have a completely enclosed run. It is 5.5' tall... and I am reading all these things about fruit trees and nut trees and bushes for in the run... and I am getting a little confused. I will have 13 total chickens... 5 bantams, 8 standard... (not sure if that matters) and I would like to be aboe to put in a tree or 2, or some bushes or something that they would enjoy int heir run but I have no idea what the best idea would be. I also don't know what - if anything would be poisonous to my girls. Any insight and assistance is ridiculously greatly appreciated.
