Eucalyptus trees demolished our coop here in Calif bay area. All but 1 chicken survived. Need plans ASAP for a 8x10 or 8x8 chicken house/storage unit. We have a wooded area & have all the preditors known to chickens especially racoons. The demolished house lasted 20 years with a 3/4 in plywood floor on concrete blocks. Biggest problem was interior layout. I want to keep the ladies confined to one area of the house and I will need access to the chicken area for adequate cleaning!Good interior plans would be most welcome. thank you.
