Peace, mercy, and blessings of God be upon you. May God bless all your times with goodness. We have the "Alif Plus" incubator with a cooling system, meaning summer won't stop your production, and you don't need an air conditioner. Put the eggs in and trust in God. It was used for only 42 days, and only the first five shelves were used, the rest are new. Its advantage is that you can control the turning path, you can enlarge or reduce it. I used it for geese, ducks, and turkeys, and each type was of a different size. The location is Rawdat Sudair. The price is 2500, and may God bless whoever buys it.
