I have 4 hens who have free roamed the yard this summer and fall and frequently spent time in our vegetable garden. We are fencing in the garden area this week as well as a separate portion of the yard just for the chickens (they have a coop and run but I let them out a few hours a day when we are in the yard to "spread their wings"). How long until it is safe to replant in the garden space? There is plenty of material on composting but I haven't seen anything on planting where the chickens have pooped while moving around the yard. Any help would be appreciated.
