Hached 36, kept 15, sold the rest. Build an outdoor pen after the weather warmed up. Used to bring them in at night. Checked them a 2:00 pm, 10 were dead by 4:00pm. A swarm of TINY flies came in and drew so much blood it killed them. The remaining 5 were almost dead, used a heat lamp to bring them back. Kept the remaining 5 indoors for two more weeks, then outside with the rest of the flock. Everything was fine for the first day. The second day I woke up with the rooster crowing. Went out and found the remains of 4. One survived, the rest were un-recognizable. Thats it for me.
