I have been looking and reading the tread about brooders at the top of the page. I notice a lot of the larger brooders are just screened cages of some sort. I could not find one that answers my question. Is the temperature in and around the brooders at 70 give or take? My heat lamp only heats an area where the lite hits the beading. Don't chicks need the whole area they are living in to be the needed temperature? (- 5 degrees per week) My brooder has solid walls with a caged top that I lay a piece of insulation over to keep the whole area the required temp. I hope I explained this well enough to get a good answer. Chicks will be hatching next Monday so I need to be ready. John
