Hi, quail newbie here. I have 14 Jumbo brown's in a brooder, in the garage under a red heat lamp. They are 3 and 1/2 weeks old. I have been reading that at around 6 weeks they will lay eggs if they have additional light. Does the red heat lamp count? Also, how long do I need to leave the heat lamp on them? It is getting really cold at night this year. Around low 20's. Should I start pulling the light away? They just bask in it now, sprawl very comfortably under it. But I could really use it for my other chicks. Thank you for any help and advice.
