I do staggered hatches all the time...write on the egg the date you set it then on the calendar the day it's due so you can remember to lock them down on the 18th day...there is just 1 thing you need another incubator to hatch in...if buying one isn't an option then make one...just make sure you get a hygrometer because humidity at hatch is a huge need!! I've made them out of those plastic tubs that you get for storage and a light bulb thru the lid....taped tight!! but make sure you have the proper humidity! can't stress that importance enough! I've read people finding hydrometers at walmart...I got mine on ebay for about 14 dollarsCan anyone offer me help? I am a first timer at hatching. I was not aware that you could not continue to add eggs to the bator. I set eggs aug 17th not even knowinh if they where good lady had them in fridge unknown amount of days. Candled them 8/25 and 7 of the dozen i see movement. My problem is over last week I added eggs to the bator. The eggs that are 5 days I believe I can see black eyes. How will this effect the hatching process for the younger eggs? Any help would be great! Ps eggs are brahma and brahma/sex link mix Thanks again
