Good morning. I am new to quail. Last week I hatched out 62 little quails. They hatched out over several days starting Friday night and ending Monday during the day. I keep them in a 50 gallon tub that I set up as a brooder. I have 2 water bottles and feed as well as a heat lamp. I started losing them after a couple of days. So far 9 have died. It is a couple a day. THey all are found lying on their side with their legs stretched out. I was worried they may be over crowded so I built a second brooder with the same materials and transferred half of the survivors into that brooder. I am hoping that it was just overcrowding. Any thoughts on how I could improve? THey seem less robust than chickens.
