I have a brisnea Oct 20... I hand turn my eggs. My personal reasons, due to the size of the bator rolling it back and forth, and the limited space I have it in. (anyone turning a brisnea knows the Clunk, Clunk) Yes.. I wouldn't turn 40 eggs by hand at a time, but I don't EVER hatch out 40 eggs..lol. My wife would commit me. With 40 - 80, 300 , 500 eggs in a bator, you don't like loosing 2-3 % but that is acceptable. When you have 10-20, loosing one or two eggs is a lot. So that is another reason I like the hands on approach.
How do you do it? Well, when eggs are sitting under a hen, they are all sitting on their sides. And infact if you read you will find the best turners rotate eggs on their sides instead of sitting up. Also that poor Broody hen has to eat and drink over 21 days. Now she won't get up for long, my mine always got up 2 or 3 times to eat, poo, you know.. things chickens do. She would be quite made at me if I tilted her broody box back and forth. Nature I guess knows a little better.
I mark my eggs with a No 2 pencil, for me... I put egg type (BR, RIR) ect, and I put an X on one side, and a O on the other. I turn them when I get up, after lunch, and before bed. So.. for me that is 6am, 1pm, and 11pm. I candle after 7 days to look for development. I print out a 25 day calander with my pull days listed, lock down, and instructions Just in case I'm not there to turn. I record my temps, RH, and candle information and if I make any adjustments on the calender.
I do use the rails though. I use them for seperators between the questionable eggs, and the good to go eggs. Also after day 14 I use them to seperate breeds. Stack them and when the chicks hatch they can't make it through their little chicken jail.
On day 7 if I see some development, but questional, I , with my No 2 pencil, put a question mark on the egg in question. If the development is right on, I put a checkmark on the egg. on day 14 is my first pull date, any eggs that are not developing, I pull em. I check the question mark eggs, if they are good then, the get a check, if not, pull. I check again on the end of day 17. On day 17 all you should see is the Air sack, and black. ( I can't lie, I candle a LOT but those are my decision days)
My turning schedule is as follows... Set X's up at night before bed. In the morning I roll them to O, after lunch I roll to the X, before bed Back to the O, next morning to the X, lunch O, Bed X. So it will be X Set
O X O End Day 1
X O X End Day 2 O X O ect..
It's just the way I do things. Or as my kids would say.. That's the way I roll.
