Coop flooring question

[Folly's place]

I see no reason for a wood floor, and prefer either well drained dirt, or concrete, with a predator barrier. Mary

Insulation is a 6 of 1, half dozen of the other kind of thing.

It can help to deter cold transferring thru the walls and floor, and slow heat gain thru the roof/ceiling. But as far as it 'holding heat' in a building (like a house) the ventilation needed in a chicken coop makes 'holding heat' moot.

It will raise your costs significantly, not just for the insulation itself but having to sheath the inside walls to keep the birds from eating it. Plus that scenario sets up nice housing for rodents and insects, and if they do get in there are much harder to eradicate. Some say foam insulation, full cavity fill, is less likely to be infiltrated by pests...but....

IMO insulation in a chicken coop has more cons than pros. Plenty of cold climate coops don't have it.

Here in Florida the cold isn't too much of a factor most winters. We have had a few 22° nights but the cold doesn't linger. The next day by noon it will jump to the 40's.
All our birds huddle side by side holding whatever heat they have. We will clamp hot lights staggered and roost close by.
I have found that insulation is a choice material for rodents and unwanted insects. Safe harbor for mother rats to bring more and more baby rodents into the world. Especially near a high quality food source and water. Rodent Holiday Inn.
My opinion of course.
