I know I googled here a lot when I started hatching guinea's - so hopefully this thread will be indexed, too. And, help someone out. I started with 36 eBay shipped pearl gray guinea eggs. Shipped from Oklahoma to Indiana. I paid a little over a dollar an egg shipped. Let them sit a day and warm up to room temperature before they hit the incubator. I am using a Styrofoam hovabator with auto egg turner. Temp is hard to adjust and it did vary. I adjust by plugging holes and laying a towel on it and being patient! I probably hatched 6 or 7 batches of guinea eggs - so that is my experience level. Hatched several batches of chickens, too. My hatch rate is usually about 50% with shipped eggs. I got 53% with this hatch (so far) I don't candle and just let them go. Guinea eggs supposedly take 28 days so lockdown would be Day 25, but I lock down on Day 23 based on other hatches and other internet information. I keep humidity at 50% until lockdown, then I had hot water to get the humidity in the 80% + range - or more. I count the first day as Day 0 - so one full day is 24 hours. Here is my chart: Day 0 8/14/14 6:00pm on incubator Day 1 8/15/14 Day 2 8/16/14 Day 3 8/17/14 Day 4 8/18/14 Day 5 8/19/14 Day 6 8/20/14 Day 7 8/21/14 Day 8 8/22/14 Day 9 8/23/14 Day 10 8/24/14 Day 11 8/25/14 Day 12 8/26/14 Day 13 8/27/14 Day 14 8/28/14 Day 15 8/29/14 Day 16 8/30/14 Day 17 8/31/14 Day 18 9/1/14 Day 19 9/2/14 Day 20 9/3/14 Day 21 9/4/14 Day 22 9/5/14 Day 23 9/6/14 took off turner and increased humidity Day 24 9/7/14 one pipping this am; now 2 this pm Day 25 9/8/14 4 chicks this am. 8 keets by 6 pm ------------------------- Day 26 9/9/14 10 keets this am; 14 by 6 pm Day 27 9/10/14 14 keets this am. 15 by 6 pm Day 28 9/11/14 15 keets this am; 17 by 6pm Day 29 9/12/14. 19 this morning; but looking at remaining eggs, I think they are done.
