Yesterday morning I had 24 chickens and 10 guineas. Last night at dusk, I had 24 chickens and no guineas. All of my birds return faithfully to the coop every night. The guineas will occasionally try to roost on top of the coop or in a tree next to it but they have NEVER just not shown up at bedtime. I've looked and looked all around the property (23 acres) and not found any sign of them, not one feather. I hope they are just wandering and will come home tonight. What do ya'll think? Do I give up hope? Have your's ever just left? We live in a very rural area and I don't know anyone around that has guineas. There is one neighbor who has 3 chickens, but that's all the poultry around other than mine as far as I know. I'm having a problem with hawks and occasionally hear coyotes in the woods at night, but I can't imagine that something would get all 10 at one time. I'm at a loss.
