A few updates: My last hatch which ended two weeks ago was much better than the hatches before, but not where I want to be. I had 22 out of 41 eggs hatch with 2 others not making it out of the shell. The Brinsea thermometer helped a lot although I only got it a few day after starting incubation. I still had a prolonged hatch and lost humidity rapidly after I took the first chicks out after 24 hours. In the meantime I bought a Genesis incubator and it was delivered a few days after the hatch completed. But, the next day the new incubator was off to my cousins place for duck eggs! They bought a few ducks at the local auction and found they could sell the eggs at their produce stand (along with their own chicken eggs) for $4.50 a dozen. With only 4 females and 4 males, they needed more laying!
My New Hampshire project is likely ending. The rooster was going after my wife and kids when they got eggs. He started going after me and there were a few times he jumped at the door as we were just about to enter or had just left. So he is no more. I have the new chicks so I could continue breeding them but I'm going to focus on the Delawares which may still be a month away from having eggs large enough to hatch. I have considered putting the Delaware roo in with the NH's which is a cross that has interested me. The other problem I saw was feed conversion. Without detailed records, I was going through a $15 bag of feed in a week and was getting less than 7 dozen eggs. That's over $2 a dozen just in feed costs. Either I need to find cheaper ways to feed or I need to get rid of chickens since a dozen eggs a day is plenty for my small family who rarely eat eggs for breakfast.
The "good" eggs at costco are 6 a dozen now.
