whats wrong with my african gosling?

[charmayne]

i received baby goslings threw metzer farms.com and i am concerned about the one african. he pulled out the feathers or fur around the white chinese gosling 1 purchased 4 of them threw the mail. 2 african and 2 white chinese. now the one he pulled the fur off of you can see bare skin. i watch this mean gosling and he does it to the rest of them to so i seperated him from the rest. he also moves his head with his beak open[ like he is catching flies almost] and its like he does it and there is nothing in front of him. the rest of them do not do that. i have grown geese and never delt with gosling. do you think nerological something could be wrong with this gosling? he is very aggressive with the others he pulls on the other consistly. its almost like he helusinates its very strange. if anyone has exsperienced this or know what causes it please let me know. these goslings are a week old

Goslings- ducklings and chickens are all more likely to feather pick if they are in too small a brooder and bored. There may be some other issues at play here- but first- how big is the brooder you have the 4 goslings in?
