In the farmingfriends forum we have been asked about brooder temperatures for ducklings.
the temp in his brooder is about 93 degrees F. Is that good? or should it be different? Badoodle
If the duckling is moving away from the heat lamp, is laying down alot and panting then the temp is prob too high, if the duckling is huddled under the heat lamp then too low a temp. moving around and sitting in different places usually means the temp is right. The link that Mo gave says, The duckling will need a temperature in the brooder of about 86 degree fahrenheit day one and then by day 7 about 81 degrees.
Once your duckling is dried out and strong enough it won’t rely on the heat lamp so much, like other birds such as guinea fowl.
