The think I'd worry about in a setup like that with tiny chicks is that rats and snakes can still get to them through the chain link. (I'm guessing that the little ones wouldn't be able to get to the chain link and go out of it.)Excellent ideas.... last time I tried to brood in the house I had em on a plastic card table and the floor Still looked like yours.... Only mine was much much much messier....
Now that I no longer have cats I am going to do this out in my green house room... It is open to the outside with only a chainlink separator to keep large critters out..... Hmmm I have water out there and power too.... Gawd .... thank you for giving me a "danger Will Robinson" idea...
