I have 2 Sebastopol goslings, Tiki & Sparrow. I hatched then together. They are 2 weeks old. Sparrow constantly nibbling on Tiki's back, he is going bald ! Anyone every have this issue...... what should I do? Here is a picture fro the other day, but it is getting worse. No blood or anything YET! I would like to avoid that. Sparrow is on the left, Tiki on the right. I know they are wet, they were playing with my DD in a puddle after the rain. But you can see the missing down.
