I bought 120 eggs from jimsbirdhouse. He lives nearby so I thought it would be a quick & simple ship to me. Which it was I received the eggs the next day. They were all in great shape & packed well. I let them sit for 24 hours & had my Brinsea 40 DX fired up & holding steady temp & humidity. I loaded it up & 23 days later they hatched not all but a bunch of iddy's. I have a big flight pen that I just recently built for them. My question to the experts is what should I add to the pen. Do they need a perch or what else any tips will be appreciated. Here's the pen. Thanks 7L
