kind of off topic, but this thread seems to have run it's course anyhow.
people collect eggs too long before bringing them for hatching.. I finally got a couple of them convinced to bring me eggs each week instead of waiting until they had collected a larger number of them and bringing them two and even three weeks of collecting.
I do wash the eggs if they appear dirty.
I have never had a problem with disease in the incubator..
keep the incubator clean as you can.
I have run the incubator steady for months at a time with no chance to clean it .. Not a good practice, but I sometimes have no choice because of rotating my hatches..
try to have at least a week of time between setting new eggs in with the existing ones.
you will have to learn to be patient with people.. they expect you to put the eggs in the day they bring them to you. if it doesn't work out with my one week waiting between hatches, then the new eggs have to wait..
Keep a written schedule of the eggs in the incubator. do not expect to remember anything. write it down..
mark each batch of eggs, whose they are, date of lockdown.. believe my, you will not remember.. I have had at least ten individual batches of eggs going at one time..
if you have a need for chickens. do the incubating for half of the chicks that hatch..
keep it local. don't try to get into shipping chicks.
I had sources where I could buy hatching eggs for regular eating egg prices.. those I would pick up .. stay away from shipped eggs.
too many shysters out there to take a chance.
and besides , even fertile shipped eggs are not a good risk.. if you get 50% hatch rate , I would consider that high..
even if you pick up fertile eggs yourself. don't put them in the back of your pickup truck.
try to give them as smooth a ride as you can.
