We purchased new incubators this year. We have 6 Avey incubators for sale. They are 2 years old, very well maintained, but need adjustments to their humidity and temperature controls. If you have someone who is handy in your organizations, they may be able to make these adjustments for you. We paid over $900 each for the incubators. Selling for $200 each. Each incubator has a number in the top left corner to identify. If we have noticed a difference in temperature or humidity, it is marked on the incubator.
