Oh, Lord, no...they should have been weaned off heat at about a month old...and you could have integrated them with the flock about then too. https://www.backyardchickens.com/articles/integrating-new-birds-at-4-weeks-old.72603/Our chicks are now two months old. Do they still need a heating lamp at night?
Absolutely, especially if they are inside a house and/or in a smaller tote-type brooder. Hard to find incandescent, reptile market still has them..and in red.If you only have a small hatch rate, say, about 4-5 little chicks...... can a small regular incandescent bulb work as a heating source?
The lamp is best at one end of the brooder with food/water at the other cooler end of the brooder, so they can get away from the heat or be under it as needed. Wattage of 'heat' bulb depends on size of brooder and ambient temperature of room brooder is in. Regular incandescent bulbs can be used, you might not need a 'heat bulb'. You can get red colored incandescent bulbs at a reptile supply source. A dimmer extension cord is an excellent way to adjust the output of the bulb to change the heat without changing the height of the lamp.
