I am also on day 17 lockdown, good luck. I have 2 store foam incubators, one with turner and fan, one without.(I don't use both at the same time.) I let them dry hatch first 18 days in the incubator with fan and turner, then move to the still air with humidity during lockdown, Rope helps with keeping eggs tilted, and not soccered by hatching chicks. I would use homemade incubator in emergency. I have had good luck with homemade ones in the past. I am happy with my current incubators. I like to keep one incubator pure from the hatching process. It has never been hatched in.
