No stupid questions!! Actually, that is a storage bin which I got for $5 or so at WalMart in the laundry or storage area.... they are plastic and stackable and make awesome broody nests. If a hen gets broody and nests somewhere I don't like I can move their nest into one of these bins and leave it in place for a day or so, then simply cover the broody with a towel and move her (bin and all) to a place of my choosing. I also use the bin in our established broody hut area in the coop, once the hen hatches we can pull the bin for cleaning and put it back or remove it completely, depending on size of clutch and temps, etc... I will see if I still have pics of it from when we got them.
I thought it looked familiar!!! I know exactly what you're talking about!!!
I can see them being perfect! You're brilliant!!! Very resourceful! I'm impressed!!! ;-)
