Hey all!   Glad to hear you like the designs.   The same graphic artist / designer did all of them.  All the designs (well, except for "Cheep Therapy") are original artwork.   He's actually a member of this forum but doesn't have chickens (yet).
Regarding Paypal credit card payments:   I'm totally baffled by this.   Other credit card payments via paypal are going through just fine, while other have tried multiple cards and are still having a problem.   I'll do some searching to see what I can find.
