Hi, I am going to be using my friend's dog crate for my third brooder, I have 8 b/o chicks who are about 4 weeks old now. I just want to get an idea of how to keep the shavings in the crate as there are large areas where it will be kicked out. I was hoping to keep them in my dining room until they go into their coop. The basement is an option but I feel they'll be lonely down there as it's not an area we use very much. Also, how old should they be until they are ready for their coop? It's still fairly chilly here in the Northeast.
