Hi, I'm raising 5 chicks indoors. I put them in one of our bathrooms and they live inside a portable cage I bought online. I thought this would be ok, and I would just keep the bathroom cleaned and vacuumed. For the past couple weeks I've noticed a lot of black dust which obviously is coming from their feathers (they're all black, Black Copper Marans breed). But now I'm noticing this dust is going farther beyond the area they're in. It's Jan. 1, they are 6 weeks old, fairly decent size and I'm wondering if they would be ok outside? The dead of winter hasn't even hit us yet, though, and they've never experienced being outside. So throwing them in the cold doesn't sound like a good idea unless I heat whatever pen I use. I don't know what to do, but this dust is just not healthy, I'm sure. I do have an air cleaner in my bedroom, which is just outside this bathroom, but this is getting worrisome. What can i do about the feather dust? And can they be introduced to the outdoors in the beginning of winter? Thank you for any advice.
