My hatches are gradually getting larger. Up to now I have just put all my chicks in a brooder which has a single 100 watt infrared bulb and have had no trouble with up to 2 dozen in a single brooder. I have several brooders and heat lamps so figured it was time to ask how many chicks or poults are OK undr 1 lamp? Do not want to overcrowd them resulting in trampled babies.
