I just put in eggs in my incubator I got from the farm today. All of them are brown so I'm not sure what kind of chicken i'm getting (either RIR or Leghorn). I got 2 dz in which i marked 12 with 1-12 and the other 12 with A-J. I put them in at 2pm and the incubator is heating up again and the humidity is 35% March 4th is Day 10. I thinking i'm going to candle them then but I might candle day 7 not sure... One of the eggs is kind of small. Does size of the egg matter?
