On July1 i nucubated 6 bantam eggs I bought online...on Jyly 8 I added 4 eggs from a neighbor farm. On July 20 and 21 I hatch 4 of my 6, but didn't have the heart to take out the older 4. They went through lockdown with no turning and increased humidity. As soon as I removed the new chicks I cleaned out the bator, lowered the humidity and candled the eggs which all showed live chicks. Now is day 18 for my last 4 eggs. Do I lockdown and raise humidity? Tried candling last night, but so dark inside couldn't see movement, but a well defined air sac. I know from reading on here after the fact that I was playing with fire. Since there is no bad odor should I go ahead as usual?
