Here are some photos. I think you can view larger by clicking on them.
This is Penny, the one that has lost the toe. It went all black and mostly dropped off then the vet just took off the last little dead bit. She said it was super close to the bone.
Its still very swollen but she is on antibiotics Just noticing the same toe on the opposite side looks like its going to do the same thing as there is no nail there either.

This is Alfie

And this is Captain. I am going to have to soak her toes or something as I couldnt get that hard brown lump on the toe nail sticking out the right off.

The fourth one is perfectly fine.
The two frizzles are from one set of parents, the sikie (first photo) and the one that is okay from another.
This was when they first got out of bed :-) They are in a covered large birdcage with newspaper and paper towel on the floor and a heat lamp next to it of a night. The paper is being changed 2-3 times a day.
During the day when we are at home we put them outside in a little chook pen we bought on grass. It doesnt look very secure so Im not trusting it when Im not home.
They are 5-6 weeks old and we have had them a week and a half.
They were kept in a laundry on a tarp the day we picked them up. It was ready for a clean but I wouldnt think it was more than a normal days mess considering how many chicks were in there. They definately weren't on wet icky ground or anything.
Help! Worried we are going to loose even more toes!
