Hi. I'm new to chick raising and we are having a strange change of weather where it is supposed to get to 108 degrees tomorrow. Today was unexpectedly at 104. My chicks are almost 3 weeks old and have a brooder box inside a little gated space inside a cement garage with an old box as a "ventilated lid" so they don't fly out.
Today, it probably got to about 90-95 degrees in the garage at the hottest (it was still 90 when I went in to check on them around 8pm tonight). I had a fan running all day and their heat lamp pointed up so that they still got light. But they spent most of the day in the space that got some of the fan blowing on them.
I'm worried about tomorrow. I went and opened up the garage to let in some cooler night air tonight and got the temp inside the garage down to about 85 (its 88 outside still!) but I can't leave the garage door open due to outdoor predators (like the stray cats I've seen around our place lately).
What do I do to help them survive tomorrow? After that, it should be more like in the 90's this week and once the garage is cooled down, I am able to run the fan and it stays at 80/85 inside the garage.
What should I watch for or be concerned about?
I've put two sources of water for them (one inside the brooder box and one outside of it) and I plan to put ice in both of those sources of water.
this whole chick raising business is trickier than I expected it to be!
