I am pretty sure he raised coturnix quail. they were nice sized..haha, maybe he just fed them well .
He would just wrap some heavy duty plastic or tarp around their cage, keeping the drafts off of them.
That worked for him, although I like your set up too, but that lamp has got to get pricey running all winter.
We would like to get into quail in the future, they are pretty easy going..not very long lived from what I understand, idk..maybe i am mistaken.
Have to finish the long run, get a roof on it before we set-out into any other adventures.
Have what we need for rabbits, just waiting for that roof, not getting soaked while taking care of the animals is tops on the list these days.
Mine are coturnix also and I've heard that they only live like 2 years or so? I always have heat lamps going anyway so it shouldn't be much different than normal around here lol
