Do you prefer using a broody hen or raising chicks with a brooder setup?
Depends on what I need the chicks for. If I want friendly pet chickens, I raise them in a brooder in the house, so they can get handled and socialized as much as possible. If I just want utility chickens for eggs or meat, then I have a broody raise them, because it’s less work for me and it doesn’t matter that they aren’t as socialized.

What’s your favorite bedding for keeping things clean and safe?
In the brooder - sand is the best! I scoop the poops with a reptile scoop (cat scoops have big holes and the tiny chicken poops fall through them). This makes it REALLY easy to clean the bedding, and it doesn't waste any bedding or money, because I keep using the same sand until the chicks leave the brooder. With shavings or other similar substrates, you have to keep throwing out and buying more and more bedding. I have raised several generations of brooder chicks using sand only, and have never had any problems. I use play sand from Home Depot. Easy, clean, and fun for the chicks - they love scratching through it and dustbathing in it.

Have you tried different heat sources like lamps, heating plates, or even natural methods?
I only use DIY heating plates. I don't like the idea of a lamp - in addition to dangerous, it's also very unnatural for the chicks to not have any darkness 24/7. Chicks have circadian rhythms like us, so the non-stop light is disruptive and stressful. Plus, they have an innate need to snuggle under something for warmth, and, being that they don't have a mom, the plate is the next best thing and satisfies that need.

How do you transition your chicks from brooder to coop life?
I have sectioned off part of my run with chicken wire, and I use that section for introducing new chickens or isolating injured chickens. They can see each other through the chicken wire, but can't get to each other. Unfortunately, my setup doesn't allow for the coop to be partitioned similarly, so the new chicks have to overnight in the brooder during the introductory process. So I take them outside in the morning, and bring them back into the house at night, for the first 2 weeks or so. Then I open up the divider and let them mingle with the flock. My coop is roomy and has multiple roosts, so the chicks can have their own area out of pecking range of the adults when they go to bed. I pick docile, non-confrontational breeds, so while the elders are always unhappy with any new additions, they don't draw blood or pluck feathers. Just the occasional squabble to remind the youngsters who's boss.

And of course… what’s your secret to keeping pasty butt at bay?
Use a heating plate instead of a lamp! Lamps force extra heat on the chicks and it's hard for the chicks to get away from it and cool off. Even if the lamp is over one side of the brooder, so theoretically there's a "warm side" and "cool side", even the cool side isn't very cool. Overheating is one way chicks can get pasty butt. That's one of the (many) things I don't like about lamps. Not only is the constant light unnatural, but the constant heat is, too. With a hen, chicks aren't kept at 95 degrees 24/7. In fact, in the spring when hens tend to hatch out chicks, it's quite cool outside. And yet, little chicks have no issue walking around in the crisp cool air, only going under the hen periodically to warm up, then back out they go. A heating plate mimics this, and allows the chicks to regulate their own body temperature better. They don't overheat and develop pasty butt. With a lamp, they are always in a hot environment, even with a "cool corner" - it's just slightly less hot, it's not cool.
In my many years of rearing chicks (both in a brooder and with a broody hen), I have only ever had 1 instance of pasty butt. It was a chick that hatched with a hernia and was a little weak, so I kept him in the incubator a little longer. I think he got too hot and dehydrated, and developed pasty butt as a result of that. I washed his butt and he was fine after that. Grew into a beautiful rooster. I haven't had other instances of pasty butt.
