The other problem is that our current birds free range... So I am not sure what to do with the new ones during the day. We do have a nice, roomy run that our girls could be confined to for the month, but oh, how heartbreaking to do that to them in the Spring! They will not forgive me soon.
Forgive me because I could not read too far back in this thread, (it's a whopper!) so I am not entirely sure what you are trying to do with T-Shirts. But $15 a shirt? That's craziness!
I screenprint, and depending on what you are trying to do, I could surely do it for less than that if you want. Let me know if you're interested.
