looking for advice on temp hatcher

[Newbydoo]

So I am ending up with 3 different batch of eggs in my incubator. only 3 of 12 were viable (batch 1) so I filled the empty spots with new ones and only 2 are viable so of course I added more for those empty spots and I can't tell yet if those are fertilized for a few more days. now I need to make a temporary hatcher for the first batch of 3 eggs since they are going on lock down in a few days... Any quick way of making one?.. I don't have wood but do have a small cooler.. any help is appreciated thank you

You may be asking about a BROODER, not hatcher.
A small cooler is somewhat small.
You need something larger, like a large cardboard box. But there is a slight danger using cardboard. Your brooder needs a source of heat to keep new-hatched chicks warm. A safe alternative is one of these.

Feed store like Tractor Supply would carry similar in their stores, cash and carry.
