After six years of keeping guineas one of our hens presented us with 17 keets in late September. We put them and mom in a raised covered pen with a heat lamp. Lost a few to begin with but the majority were healthy and active. About a month ago when they started to attempt to fly we moved them into a vacant stall in the barn. ( again with mom) and provided them with some roosting branches.They all seemed healthy and happy. We were just about to let them loose when yesterday my husband went in to feed and saw one fly right onto a wall, which broke his neck. Discovered six more on the ground dead so presumably same scenario. He immediately released the balance but two of those were very lethargic and wobbly and died shortly thereafter. The other 6 or 7 were fine - came outside and started pecking , scratching etc. But by afternoon all but 1 had disappeared. We hoped they would turn up but it has been over 24 hours now and no sign of them. I am absolutely in shock that we kept these babies safe and healthy for almost 3 months and then in the course of a day we went from 15 keets to one???? What could we have done different? I feel horrible - like I did not protect them sufficiently. .
