So what you’ll wanna do is have your brooder set up two days before they arrive. Why? Because A) sometimes they come a day or so early and B) you want it warmed up a couple hours before they get to you.
Make sure it have the heat lamp to one side of the brooder to give them a chance to cool off. When they first arrive, as you take one chick out the box places it’s beak in the water to teach them to drink. Food comes naturally. Give them 24-48 hours to get decompressed from shipping stress.
Typically, if you run/tractor is tightly shut up (1/4in holes all around) you can put them out to pasture at 2 weeks. Bring them back to the brooder for week three. After that I let them roll. No heat lamp after week 2. So they will get used to dusk to dawn living. They will bunch up at night if they get cold. Offer grit when you put them on grass. Free choice. Come back if you need any assistance after that.
Or for that random question, or when you freak out cause something happens and we will help tell you it’s not that bad!
