Hammer drill is faster and keeps the bit contact area from glazing which makes the drilling take longer. Concrete blocks should drill just fine with a normal drill and a masonry bit.
One more item is that hatching eggs can be shipped via UPS or FedEx.
One of the worst things for hatching eggs is to be shipped by air in an unpressurized cargo hold. The changes in pressure due to the changes in altitude can destroy them.
Given the choice, I have hatching eggs shipped by...
They're all bad but less can happen to it sitting there waiting for you than the additional transport and final toss delivering it to you.
Some of the harm is unintentional such as sitting hatching eggs by a heater duct to "keep them warm".
My experience is that eggs that come through a major...
FYI, if shipped eggs do not develop, it does not necessarily mean they are infertile. Eggs that go by airplane in a non-pressurized cargo bay can be destroyed by the changes in altitude. They will not develop even if they were definitely fertile to start with.
I found no difference when I set shipped eggs immediately with the turner on from the start and any of the other recommended practices of letting them set and no turning. Experiments have proven that the most important time to turn eggs is during the earliest part of incubation..
Shouldn't be a problem at your elevation. My friend in Buffalo at 4700' elevation doesn't have the problems hatching that I have at 5200'+ elevation.
She recently had a 100% hatch of chicks.
That wouldn't happen here. The USPS does not deliver to rural houses. You have to pick things like shipped eggs up at the post office. You don't get to see them throw the boxes around.
Too bad you didn't video it so you could show his supervisor.
Don't be in too big of a hurry to buy into the higher humidity at higher elevation proponents.
4200' isn't that big of a deal. It's the ones that are over 5000' that have more of an issue. The issue isn't the humidity but rather the lower concentration of oxygen. Especially the build up of...
