Every part of my incubator gets cleaned with bleach every time in between use (including the egg turner if I'm using it). And rinsed well. I leave the two vents open (is a farm innovators incubator), monitor temp and humidity every couple hours, its in a place with little temperature fluctuation. Its a forced air, so there is circulation. I use three thermometer/hygrometers in it. Two down on egg level, one on the window on top so I can check temp differences, etc. Perhaps I will give the oxine a try. WHen I've done eggtopsies, there hasn't been bacteria or signs of it in most of them. The ones that made it today 18 I think drowned in the shell because I hiked the humidity up too high (added more water before giving it enough time to equilibrate). Some I checked from my OEG weren't fertile, some were but didn't develop. I haven't recieved any washed eggs so far as they have all been from folks here on BYC who know better. The eggs are allowed to sit in the room where the bator is for at least 24 hours before I candle to check air cells. If the air cell is detatched, they get set with the fat end up for 72 hours prior to being placed in incubator (assuming the cell reattatches or I decide wth and do it anyways.) I wash my hands before candling, which I do on day 3, 7, 14, and 18 for chickens. These quail I candled on arrival and on day 12. I don't handle the eggs alot, and I don't mess with the incubator alot. I don't have any hens that are going broody (EE and cochins are all too young atm) so I can't stick them under one of them either LOL
(And maybe I should have posted this somewhere other than the auction thread... my apologies!)
So you're running at 100.5 in a forced air bator?.. that's part of the problem.. run it at 99.5.. you CAN drop the temp by one degree at hatch for the chickens (I wouldn't for quail).. but the temp for forced air bators to shoot for is 99.5 for chickens and quail..
when you candle the air cells are they on track?.. if so then the chicks shouldn't be drowning in the shell... adding a lot of water at once won't cause drowning (lol.. unless you are submerging the eggs).. it's caused by the overall humidity being too high during the entire (or majority of) incubation.. which would be evident by finding air cells that are too small for that day of incubation when you candle..
by the way.. if a chick dies from bacteria you won't SEE the bacteria.. all you will find is a dead chick unless it has begun to rot.. which it would have to die well before day 18 to rot enough for you to see decomposing goo..
