You can tape the toes straight. Cut a bandaid down to size or you can use painters tape. Something that comes off easily. Don't leave the tape on for more than a day.
I want buttons again. They are so cute, and even with objects to compare size, you just don't know how tiny they are until you see them in person.
They're adorable.
Assisting is a tricky question. Usually chicks that have problems hatching have problems for reasons. I will assist, but only about 20% of the chicks that are assisted will make it. The worst is assisting a chick then having to cull it later.
It's your choice.
