I have about 30 button Quail eggs in the incubator right now that are due to hatch either the 30th or the 1st. I can only keep two pairs of them for breeding. I was wondering how soon you can tell the sex of them? Once i can tell the sex and can seperate my two pairs i will need to get rid of the rest. I dont know how many extra there will be, but I will have free button Quail as soon as i can sex them!
