Looking again, there are many subtle differences like the number of feathers in the tail. I’m staying with my original guess of 7 as that seems the most obvious. However, those saying all are different make a strong case. 👍
The eye on #7 is different.
7,5,2&3 just at a quick glance.
All are different
I wondered that , but I only got 3, 5 and 7.
I saw two different ones right away
I haven't seen a difference yet, other than the numbers
This is a trick because they all have differences
2 & 7 are different
#2 shows 3 toes, and #7's eye is looking up.
Edited - looked back, #3 has a different tail.
I do see that two and seven are different.
Number 2,3,7 are different.
