So many people have different opinions, and being new (9 weeks) with chicks I need some help. We live in NJ. The weather is turning colder and we will be moving our 10 chicks ( 6-9 wk olds, 4-7 wk olds) out to their coop. We have a 4x6 raised coop with a 20 foot run attached. Do they need a heat lamp on during the winter? The weather can get quite brutal in Central NJ. The coop is really well sealed though. And how often do you feed? Should you have feed and water available 24/7? So, 1. Heat lamp in coop?? 2. Feed and water 24/7?? Thanks for the help!!!
