Holes in egg boxes necessary?

[cletus]

Really depends on who you talk to as there are pro and cons on the question. There is also anecdotal reporting to support one or the other. I think the majority of keepers would say no to needing holes in the incubation tub. On the other hand I think most would say yes to venting the tub on a weekly basis.

By that do you mean to simply crack the seal once a week to let some fresh air in?
