Glad you decided to join our flock!
I agree with @cluckcluckhens - I would ask family, friends, or neighbors for egg cartons. If you're in a real hurry to get them, TSC has them for 0.50.
You might be looking for egg containers. We have three cupboards full of egg cartons that we get from neighbors and our Church and too many for us. I would look and check around if you need egg cartons. Check friends and neighbors.
