Hello everyone! This is my first post I am looking to buy my first incubator and confused by all of the choices. Is there such a thing as an affordable, small incubator that can handle different sizes of eggs without having to purchase all sorts of add-ons? I want to be able to do quail (like 2 doz eggs) or duck eggs (maybe 6-8 eggs). Is there a product that will fit my needs straight out of the box? This would be occasional, small scale home use. Thank you!
