The eggs all seem too be doing good but Ill check again for veins next week . One other thing I was wondering iv seen mixed answers on is opening the egg box . Do you open it every few days for air and to check them or is it best to just always leave it closed so there's no temp fluctuation . I've opened it once to wipe condensation off the lid and It dropped 1.5 degrees but went back up to 89 pretty quick . I assume it should be left alone as much as possible tho .
