Currently brooding our 2nd round of chicks under the 12x12" heating plate. We love the reduced fire risk and the fact that it doesn't heat the room. There's been no noticeable increase in our power bill for the months we've been running it.
Setup is as easy as sticking the legs in and plugging it in. No jury-rigging a lamp rig. The legs are a breeze to adjust as the chicks grow. Some weeks, I adjust them daily, leaving one side lower than the other for different sized chicks.
Besides the ease and peace of mind, it seems like chicks benefit greatly from having a place to sneak under like they would their mom. Our first chicks are in the coop now, are super sociable, and never had aggression issues even when an exceptionally cold, wet, windy spring prevented us from moving them to the coop as soon as we planned.
I purchased the cone top. It works great, but we only use it the first week to keep tiny chicks from hurting themselves when they hop off the top. In a week, when they have wing feathers and can hop more gracefully, I swap the cone top for a cardboard template that's easy to switch out after they poop on it. The top is warm, so chicks love using the top as a roost.
3 considerations:
- Like many chicken things, size up from what the manufacturer suggests. Our 7 chicks outgrew the 12x12" plate in a month. By then, some luckily preferred sleeping on top of it anyway. Probably cut the manufacturer's recommendation in half.
- Beware if your brooder's in a room with a temp in the 50s or less. If you aren't brooding them in the house, it'd be good to heat the space to the 60s for the first few weeks so the chicks don't chill when they run out to eat/drink/exercise, which they do a lot.
- Because this isn't a lamp, I leave a dim light on (just enough to read a newspaper by) so chicks can find food & water at night, especially the first week, when it could be dire if they get lost in the dark and can't find the heater again (chicks often eat and drink at night, esp. during growth spurts).
This thing has made raising chicks a lot less stressful, and RentACoop has done a good job with the adjustable legs and easy setup in particular.
