Hi! We have 16 Gold Star chicks arriving at our feed store next Thursday. I have feeder, food, waterer, the powder stuff for the water, pine shavings and a heat lamp. I have almost finished my coop (can't work out how to get pics on byc...super annoying) and will start the run this weekend. I'm sure this is chix101 but I want to make sure I am ready for the babies on Thursday. I am building a brooder out of leftover untreated plywood from coop build. Please give me your opinion on how big I should make this thing (area needed for chix and height) Also, is there a certain timeframe they need to be in there? In town today I had 2 completely different answers for that one. Thanks for any advice.
