After much reading I realize that the sniff test it the tried and true MO for many a quail breeder/owner. I am new to quail and currently have my first set of 41 eggs in the bator , a mix of jumbo pharaoh and tuxedo; they are on day 4 of incubation as of 19 October. Being new to quail I am still trying to figure which MO of checking for viability suites me: candling or stink. My question is, for those of you who do candle or have candled: when is best? My parents were both teachers and growing up I was constantly bantered to question and figure new ways of doing things and this quail deal is exciting!! I attempted to candle two eggs today. I know for myself now how difficult the specks/thickness/color make it to see observe anything. If I was to candle again, at what point would I see anything in the egg that would prove it is really going somewhere? With chickens (standard and bantam) and ducks I hold true to not making any decisions as to tossing until 14 days. What is the quail's equivalent check-point (if I was to candle)? Also, and this just bothers me to no end: how do you keep the eggs still? Ever since learning it is best to set eggs point down I do anything and everything in my power to assure they maintain such posture. Right now I have placed marbles between certain eggs to maintain the up-right position but some eggs just always seem to slide around. Is this detrimental to the young embryo? Usually it is only one or two that slips under others and get settles on its side, and I do open the bator (strictly once a day) reposition the wobbly eggs. I'm afraid my boyfriend or I may have thrown out the egg cartons in which they came in during this weeks cleaning spree. Ideas, or should I let them be? Thanks, can't wait to hear back from y'all!!
