Hatching coturnix quail eggs Successfully The biggest mistake people make with hatching quail eggs is to add to much water to the machine, humidity is a big issue but I would strongly suggest adding no water at anytime during incubation. I certainly have favourable results by not over moisturising the incubator units.

Eggs must be turned during incubation at least 4 -6 times per day. Do not turn eggs during the last 3 days before hatching. The air vents should be almost fully open during the latter stages of hatching. Returns are not accepted due to the nature of our product, however, if you have received an unusual amount of broken eggs we will send you replacements.

Usually the hen will keep sitting if she thinks the other eggs are fertile and I have read that the hen can feel movement in the eggs so will keep sitting. Quail eggs take about 17 days to hatch and hen eggs take 21 days.

The incubation time needed for fertile eggs is shorter (14-17 days) compared to Bobwhite quail eggs (23 days). Coturnix may start laying eggs as early as 6 weeks of age compared to 16 weeks for the Bobwhite. HISTORY: Japanese quail have been widely distributed in Europe and Asia. Egyptians used to trap large quantities from their farm lands for meat. In Japan, these birds were kept as pets beginning in the eleventh century.

Some say that you can use quail eggs up to 10 days old for incubating but we would not recommend using quail eggs older than 7 days. The eggs should be fumigated after collection but some breeders do the fumigation when the quail eggs are placed in the incubator for hatching.

Less is more. In fact, many people have great success doing a dry incubation with their quail eggs. If you choose a humid incubation, aim for 45% humidity for the first 15 days and increase to 65% for the final three days. For temperatures, quail eggs incubate at a similar temperature to chicken eggs. If you are running a still air model incubator, aim for a temperature of 102ºF and rotate the eggs around the incubator when you turn them. If you are running a forced air model incubator, aim for a temperature of 100ºF.

90-94 °F. It is best to have your machine running for at least 1 to 2 days prior to setting your eggs. This will ensure that your temperature and humidity are exactly where they should be prior to putting the eggs in. Above is a chart showing the recommended incubation temperature and humidity for bobwhite quail eggs. Your eggs are incubator ready, there is no need to wash the eggs. Always have clean hands when handling the eggs as your skin produces oil and can clog the pores of the shell. Always set your eggs with the big end up. This enables the embryo to remain oriented in a proper position for hatching.

If your incubator has a separate hatching tray then put your quail eggs on the hatching tray. Japanese Quail chicks will begin to hatch from the 16th day of incubation, but most of them should hatch on the 17th day. Any quail chicks that hatch after the 18th day will probably die. If you achieve 75% of hatching rate or above, you’ve done very well.

Coturnix quail go from being an egg to laying eggs in 8-9 weeks. Crazy, right? The first 17 days are spent incubating and days 18 and sometimes 19 are spent hatching. Much like chickens, there is no calendar in that egg, so quail chicks may begin to arrive as early as day 16 and as late as day 20.
