I've had my guinea fowl in a pen in the coop since I got them at around 3weeks old. I left them loose in the coop with everyone locked up for a week and then the past few days started opening the door in the evening. They ate in front of the door and went back in with the chickens. Today I opened it at noon and went to shut it at dark. All the chickens were in but no guinea fowl. I figured they'll be in a tree, over in the building on top of things, or at least hiding in the weeds and probably pretty safe from predators. Thinking we'd never find them in the dark we got flashlights and went looking anyway. Checked the building and my husband headed over to check the weeds near the coop. I move my flashlight in his direction and see something laying in the yard. I walk over ready to find a dead guinea fowl. Nope it's alive and there's all the others but one. They were sleeping in the middle of the yard with the bottom one jammed down in to a hole. Any faith I had in guinea intelligence is gone... How anyone can have these guys sleeping outside and not lose them all is beyond me. They might as well have been served on a plate to the local raccoon population. My husband kept them gathered together while I carried them 1 or 2 at a time to the coop. It went fine until the last one which happened to be one of my 2 slates that were so hard to get ahold of. It panicked about being alone before he could grab it and flew up into a tree. We decided even if it was one of my slates a dumb guinea was not worth the risk of trying to get up in to that particular tree after dark during a windstorm. Hopefully it's still alive in the morning and the missing royal purple appears. I'm not sure what to do with them now. I guess I could toss them back in the little pen but they were starting to outgrow it. I don't want to keep my chickens locked up with them for another week. Are people who just let these guys run about with no coop insanely lucky or what? Mine wouldn't have lasted their first night out. The few chickens I've had stay out overnight did a better job. I had to collect a coupe hens that were trying to roost on some posts once and had 3 hide out in the weeds when a predator attacked during the day. They showed up the next day just fine. Even a few 8week old chicks managed to hide out once when they escaped their pen. I didn't find them and neither did the predators before they reappeared with the free range flock. The guineas can't even find a hiding place except to have one stick it's front half down a random hole in the yard with it's tail feathers sticking up like a flag while the rest sat on it in a circle. Giant predator buffet right out in the most open part of the yard with nothing around to block the view of them.
