I have once again lost my flock. A hawk this time. They were roosting in the barn, and the hawk picked them off one by one. Now, I have 2 remaining. A rooster and a hen. They hang out around our cabin, and are the longest surviving pair. They roost under our front porch. I can never find her eggs. Rarely. I so want chickens, but nothing I make for them keeps them safe here. We are really in an animal rich area. So, free range. On average if your chickens are free range (just going where they please, roosting where they please) how many do you lose a year. How many should I have to create some safety in numbers? Thanks.
