Early Lockdown Question

[Jlreay]

Today is day 17, can I put my eggs in lockdown half a day early? I won’t have time before work tomorrow or is it better to wait until later on day 18?

its close enough ... better alittle early than late on changing humidity and turning is most critical in the first 2 weeks .. most batches i get an early one anyway that pops out on 19 ..
