Just to let you know that I am delighted with the Ovation performance. I have decided to use the Ovation as an incubator and the original Octagon as the hatcher. At the first use this approach has performed extremely well. 29 eggs were in the Ovation for incubation and transferred to hatch in the Octagon last night day 21 at midnight and by this afternoon we have had 25 hatch. Really delighted! Next batch of 30 fertile are in the Ovation presently due to be transferred to the Octagon on Monday for hatching next Thursday.
