I've been seeing that ad too.Ironically for those of you who don't see ads, the header ad I see for this post is an ad for Nestera coops featuring a tee-tiny coop.
But I notice two good things about that ad, that are not in most:
--they have real people standing next to the coop
--they appear to have a real chicken perched on top of the coop
Those two details make it obvious how small the coop is, unlike many others that are photographed to make a tiny coop look much bigger than it really is.
(Yes, I think the Nestera coops in the ads are too small for the number of chickens they are claiming can live in them. I'm just saying the photos in the ads are LESS deceptive than many others.)
Edit to add: now I see that there are several Nestera ads with different photos. So far, I see at least one person in each ad, but not all have chickens. So partial credit for showing scale.
