Thanks for your continued interest. Here's a fluffy chick picture, 5 of the chicks were in the brooder at this time and the other 3 were drying off in the Octagon. Now that it's all over and I have taken the Octagon apart to clean it, I'd say that yes, I would buy it all over again. I got the Eco with the auto turn cradle as a separate purchase, and here in a nutshell are my personal pros and cons:
PROS: 1. compact size 2. quiet operation 3. great temperature control (to within .3 of a degree) 4. good design (because there seems to be a little handle or easy-lift for everything you have to do) 5. adjustable rails to accommodate different size eggs 6. excellent directions and customer support 7. my students LOVE the yellow and black color
CONS: 1. access hole to add water is woefully tiny A straw doesn't fit in there, even folded over. The solution to this is probably obvious to everyone except me. The vent hole does accomodate a straw but it couldn't be left in obviously because then you couldn't vent the incubator 2. the "clear" plastic is very murky (it was clean) and it was impossible to read the thermometer/humidity readouts without a flashlight and a certain angle during the auto-turn cycle
NEUTRALS: cleaning was messy but it is in the Little Giant also
By the way, the other 2 eggs that never pipped still hadn't done anything by the end of the day, so a brave colleague took them outside (with latex gloves and trash bags), opened them and reported back that it looked like they quit on Day 15-ish, according to a chart of embryo development I have. I was too squeamish to open them myself. I'm such a scaredy-cat. I know many things can happen in the process of development, and since they WERE all exposed to exactly the same conditions I don't think I did anything wrong, it was just nature's way of culling the mistakes.
The conclusion: This was a blast and I'm going to do it again soon, since there's lots of people around me who want more chickens!
