digital temp control, and humidity. basically set it and forget it (except to add water) comes with auto turner. I paid 350.00 for this back in may and used it 1 time to hatch out rhode island red eggs from taterschickens grand kids. (their reds offsprings eggs). had very good hatch out of them too, but we had to give away all our chickens due to inability to take care of them anymore.(illnesses) so dh is parting with his bators. my loss is your gain. I know you can buy them right now new for 299.99 from brinsea but when i bought it in may it was 327.00 plus 23.00 shipping. send paypal payment to [email protected]
