Bugs... are so so

My bugs are so so, but still there. I am using Neem and a few other organic methods, Garlic spray... i still have a few matters in the grow room until the pest are all gone. Also chickens are keeping warm by sleeping on top of each other. Also why don't they go into the chicken box and not sleep on the floor when it is this cold???/ I have to stick them in there each night.,
