I am planning a chicken coop and run for 8 hens. Coop plan is 6x8 and run is 6x16 (96 sqft). If I use the rule of 10 sqft per hen, this should be ample for my 8 hens. BUT there are a lot of rhodadendrons in this area. Would they appreciate the jungle? I can prune the plants back. ALSO, can the chicks hurt themselves if they eat rhody leaves? What about the moss on the ground? Thanks!!!
