pretty soon. what day did you count as day one? it should have been the day after you put the eggs in. they can take up to a day or two to hatch out completely. my theory for when they peep like that it's to let the others know they're ready and induces the others to hatch. i have 2 early Silver Phoenix in there talking to eachother, one is zipping. you'll have your flock in no time! no need to worry. also, they break the air sack inside the egg to breathe before they start to hatch, so the peeping you hear is normal. good luck! sending the hatching vibes!
