Contrary to what I have read from other breeders, regarding the pair ceasing to brood at ten days, I have not found this to be the case. In fact to the contrary, I have found that they will brood up until a couple of days of fledging. This may well be a climatic situation, and depend on where the breeder is based geographically. It may also depend on how many chicks are in the nest. The fewer the chicks, the longer they brood.
Incubation takes thirteen days.
Be inclined to allow an extra day, particularly in cooler areas. The young fledge at 21 days, but as with incubation don't be too concerned if that varies marginally in cooler areas by a couple of days. The latter point on individual pairs is not to be underestimated. Getting a good pair to start with, is always a bit of a lottery, but if you have, that is the avicultural equivalent of winning the lottery. All of the desirable characteristics in this pair have a higher than average chance of being passed on to their progeny.
