For Christmas, I received the Octagon 20 adv Brinsea. Or at least I think so... it holds about 20 medium eggs. Well, anyhow, this spring we hatched between 7 and 12 chicks, but as the summer progressed, we got down to 1 and 4 chicks. We decided on this last batch to finally have a complete wash of the thing and only successfully hatched 3 chicks, and only 2 made it... I know thw humidity has been bad this summer and lots of hatches were bad with many, but is this our fault, the incubators problem, or the humidity as to why we are failing at hatching? Our humidity was betqeen 50 and 55 and the temperature between 99 and 102. And we of course stop turning on the 18th day and boost humidity and all that. But we just wandered why?! We may hatch again in november, so we wwnt the best results possible.
