My 7-yr-old son has, nay, had 14 guineas. They were raised in the house, placed in the coop at 12 weeks, and after another 4 weeks in the coop allowed free-range around the house. At first we chased them back into the run. If we didn't catch each and put inside the coop, they all huddled on the ground under the coop. Never could get them to go in for the night by themselves. Then one night we were too late. They had jumped to the coop roof and up into the pecan tree overhead. That has been their nightly roost. Last weekend we went out of town leaving plenty of food and water. When we returned there were only 9. (Not exactly the kind of math problem you want a 2nd grader to figure out, but oh well). Predators are a possibility, but no sign of foul play. Any chance they have eggs somewhere and got broody.... all 5 of them, in November?
