any cardboard will work. I used a piece from a diaper box and masking tape. I saw some picture online of people just using masking tape but my girls foot wouldn't stay open at first so I needed something more sturdy than just tape. Yes it's feathers probably will get stuck in the tape you will just have to be careful taking the tape off.
Sorry this is a terrible picture but it's the best one I could get. I gave the chicks some scrambled eggs for dinner but they weren't interested - just wanted to nap. Maybe my little curly toed one will eat some of the eggs for a midnight snack. I'm also going to get some liquid vitamin as soon as possible... I have some made for reptiles, I wonder if that would work for birds too?
Cuckoo Mama, what kind of cardboard and tape did you use for the shoe? The foot is so very tiny... Do you think the tape would get stuck in her little toe feathers? I'm willing to try anything I can to help this precious little one!
