I'm getting some new chicks in a couple months and I want to be ready for them. I'm moving the 3 hens I have left into a new house I will be building them around the middle of March. They(and a bunch more birds) have lived in the old coop where I plan to put the chicks since last May. I know you're not suppose to have chicks and adults near each other. That said, I want to clean the coop out really well before the chicks get here. Other than sweeping and vacuuming all the shavings and dust out, what else should I do? Is there any way to sanitize the walls, floor, etc?
