For only 3 chicks:
Due to space constraints this is about the biggest space available and I have no intent to keep the brooder after they move out.
That's a 25W (NOT 250W) red bulb I bought at the hardware store, not specifically a heat lamp. The bulb is ~3 inches above the floor. The floor temp right under the bulb was 100~110F. The original box is 12x18.
At 4 weeks I stretched the box out to 18x18
Now that the weather is nicer they will be ready for the coop as soon as the coop is ready for them,
