I decided that the best way to know what is ideal for chicks is to study Mama Hens and see how they do it. I was raising chicks indoors under a heat lamp and I knew there had to be a better way! That lamp heated the floors, the walls, the food, the water, the bedding and the air, when all I needed to keep warm were the little babies! We all know that the ideal situation is a good broody, but sometimes they just don't go broody when chicks are available, or they end up not being as good with raising chicks as they are setting eggs and we have to be prepared to step in. <sigh> So mimicking a good broody as closely as possible seemed to be the logical way to go. But how?
Mama Hen doesn't heat the entire space the chicks occupy. The recommended heat lamp setup has the lamp on one end and a "cooler" space in the rest of the brooder. But that space in the average brooder that folks build is usually only a few degrees cooler than the area directly under the lamp - a difference that's barely noticeable to chicks stuck in there 24/7. The bigger the brooder, of course, the bigger the temperature difference between the heated and unheated places, but it's still not all that great. Now, @Ridgerunner can achieve big differences - he's said that while the chicks are in his outdoor brooder under the lamp they are nice and toasty but on the other side of the brooder there is sometimes frost and a little skim of ice in the water. Most of us with our usual selection of brooders can't achieve that natural swing - or we panic if we accidentally do! In the coop the temperature difference between "under Mom's wing" and the rest of the surroundings can be 40 degrees or more - yet the chicks thrive. Chicks explore their outdoor surroundings, even running through a skiff of snow in the yard, and are still happy, growing, and strong. How can that be if they have to be at precisely 95 the first week, 90 the second, etc?
The short answer is that I simply don't believe they need those constant, high temps. Seriously, they don't. I know what conventional wisdom says, but in the case of chicks I believe that conventional wisdom actually runs contrary to common sense. In my search for finding a more natural way to raise chicks, I ran across a video done by Patrice Lopatin showing her new chicks being raised OUTDOORS, in a straw cave heated with just a heating pad, and the temperature out there was 40 degrees. WHAAAATTT???? And talk about happy, healthy chicks!! Then in conversations with my good friend @Beekissed , who not only raised chicks with MHP but actually hatched eggs that way too, the idea was cemented into my head and wouldn't leave.
So I did it. It started with Scout, a little chick who was injured outside while living under a broody hen. Temps had been in the 60s and 70's, then in just 2 days plummeted to minus 17 degrees. (Yeah, welcome to Wyoming!) He managed to freeze his feet at the waterer so he had to come in for treatment. That was the first time I put Mama Heating Pad to work, and it exceeded every expectation. He thrived. By the time I had moved his entire heating pad setup back outside, it was in the teens, he was just a few weeks old, and then temps dropped to 4 degrees below zero and stayed that way. He was happy as could be, running under his cave for a quick warmup and then running back out to practice being a chicken. He integrated himself back into the flock, he grew, and when he decided he was a big boy and didn't need his cave anymore he just transitioned himself from brooder to flock and roost. Talk about stress-free transitioning!
I have raised every batch of chicks with Mama Heating Pad out in our run, regardless of temperatures, ever since.. Although I learned about it from Ms.Lopatin and @Beekissed , and I knew the "whys" of this method, I didn't know the precise "hows" of making a setup and having it work. It had been very hard to find concise, in-one-place directions, and since I'm a visual learner rather than being successful with dry, written instructions, I decided to share in photos what I was learning - as I went - with others on the off chance that they, too, were looking for a better way. I never anticipated that the Mama Heating Pad thread would take on a life of its own, but there were sure a lot of people out there who also wanted a more natural way to raise chicks, and a lot of people who'd already been doing it (or something similar) and were eager to share what they'd learned!
For those of you looking for precise temperature information, shortly after bringing our first totally "cave raised" chicks home and setting up MHP in the living room, someone asked me what the temperature was under the cave. Shoot, I didn't know - I never measured. I just knew I had happy chicks scooting under Mama Heating Pad if they got spooked or needed a quick warm-up, had them climbing on top of it for a game of King of the Mountain or a nap, they were sleeping through the night from sundown to sunup, and they were thriving. So I decided to find out about those temps. A wireless thermometer under there showed me that the temp on the floor of the cave was 82.9 degrees - the rest of the room was 69 degrees. <GASP> My chicks should be dead instead of sprouting little feathers and getting stronger! The key is that the contact of pad at the "roof" of the cave with their backs turns out to mimic Mama Hen! It's soft. It's warm. It's dark. A couple of days later their brooder with Mama Heating Pad was set up outside in the run, and they never missed a beat. At a week old they were living outside in full view of the rest of the flock despite a few snowstorms! Never lost a chick or had one get sick. It worked!!
I watched their behavior rather than the numbers on a thermometer and made adjustments until they were happy. Too cool? They'd huddle in a corner, either under the pad or in the far corner of the run and cheep like crazy. That wasn't a hard fix - I just smooshed the top of the cave down a bit more or turned the heat up a notch and they were content. Too warm? They'd avoid the cave completely or hang around right at the front entrance. I'd pull up the center of the cave a bit or lower the temp a click. Done. As they feathered out more (and fast, living outside like that!) I turned the heat down one or two clicks. By the time they were 3 weeks old, the pad was turned down to 2 or 3, and they were spending most of their time on top of it or tucked around the sides, just like they do when they all start getting too big to fit under a broody at one time. By 4 weeks old the pad was off and we had almost total integration with the flock. By 5 weeks, the brooder was removed (or the current chicks totally evicted to make room for a new batch) and integration was complete and seamless. And temperatures out in the run varied between 40s during the day and the teens and twenties at night, with occasional 60 mph winds and sideways blowing snow. This year I ordered some chicks and hatched some others, timing it so they would all be about the same age. Within 24 hours of hatching and drying completely, all the chicks went outside to live, and that includes the Silkies.
My experience tells me that overprotecting chicks with heat lamps is as far from natural as it can possibly get. The heat is constant, dry, and all-encompassing. No wonder they get stressed if, after 6 to 10 weeks of that, they are suddenly expected to go live outside where the environment is totally different, it gets dark, and everything is new and scary. And having never been without that heat lamp's light and temperatures, they can't deal well with the dark and they sure aren't used to having a bit a chill, even if it's only by 5 or 10 degrees or so. You do have to watch your chicks to be able meet their heat needs with MHP - but you'd be doing that anyway with a heat lamp, right? And how many of us struggled to meet that "ideal" temperature - moving the lamp up or down, trying thermostats and thermocubes, and still ended up with chicks that were kept too warm, and then were in a total panic the first time they felt 70 degrees?
Is it perfect? Nope. Neither is a heat lamp, and even Mama Broody Hen can make some mistakes that result in chick deaths too. But by letting the chicks learn from day 1 to self-regulate, to meet their own needs as much as possible, and for me to be able to make small changes based on their behavior is the only way this lady will artificially raise chicks again. Not obsessing over this temp or that one is liberating and the result for me and for many others has been calm, strong chickens!
