[Gpdd] behavior- jealous pig

[SCOTT BILOT]

Our Bonnie went from a sick pig to a pig with an attitude.  She will go after anyone I am holding when she is around with teeth open as an warning.  She has tried to nip our 12 week old a few time just because she is asleep in my arm.  You put her down to pick up other pig in the pen and it is a race to get there before she does.  What can we do to stop this behavior or is it just her personalty?  She is usually the one on top of the sofa and rarely in a pen until lately.  She is a peruvian and about 6 to 9 months old.  She was very sick when we got her with vitamin c deficiency, repiratory infection, and bacterial ear infection.  Could this  have anything to do with it?   Thanks for your help.  don't know what to do.        Scott and Rebecca Bilot
