I have another question. Is there anything that chickens should absolutely not eat? Are there toxic weeds that will hurt them?true.... I would guess. I dont have a "normal" enclosed coop though so I will defer of others have a different opinion.
What i have learned over the years is what works for some does not work for others. Especially environmentally. My place is in the high desert HOT in the summer and some snow in the winter... but very very dry... so my coop areas are only sheltered over the roosts.
