Where in the world do you live? I live in North Alabama, and my chickens live year-round in an open-air covered coop/run combo. I brood in my non-climate controlled garage for a few months in the winter/early summer, but after that the garage is too hot for them. Chickens can live just fine down to -25F to -35F for standard chickens. I keep the door to the garage open a lot during the day when brooding, and they have sections of their brooders that are the same temperature as the outdoors, even when it's very cold out. They get acclimated to the outdoor temps quicker that way. They are happy in much colder temperatures than I thought they would be. Granted, I have standard fowl, and not silkies.
There are several articles in the Articles section that talk about brooding chicks in your run, and how to brood chicks outdoors. I would encourage you to look into that.
The way you are managing your chicks and your hatches and your brooding is not working for you. It's having a negative impact upon your life. Please take the steps necessary to return peace to your life. You will be much happier once your house doesn't smell like chickens.
