Hi, I have silkie eggs from my birds in the incubator due to hatch on the 7th. I have 20 that look good to go. A week after I put these in I put in more eggs and there are 16 out of them that are growing. The plan was I was going to use a styrofoam cooler and a heat lamp and a sponge for humidity to hatch them in so I could do the stagering hatching. But now I'm getting nervous and I know I won't sleep for 3 days as they hatch so I had another idea. I have 3 broody silkie hens in my coop that are my most broody hens. I was thinking I could have them babysit the later eggs for a few days while the other ones hatch. I could split the eggs between them. The only thing is it's still getting under 30 degrees here at night. Will they be able to keep the eggs warm enough? Should I put something under their nest boxes so it would be warmer on the bottom? I have cardboard boxes for them that I just change when they get dirty. Do you think this will work and do you think the eggs will be okay? Thanks for any advice!
