Well I'll tell you my own vet's stance on it,and any vet's credo is
supposed to be "First Do no Harm". In your birds case,I would think
maybe the vet feels it's an extreme enough case to need
medication.I had one case that required meds,an Umbrella that had
been badly abused by the previous owner,he was so nervous he shook
when the vet went to take him,he was just terrified of
everything,and he was ripping skin,which can cause infections,etc.
I'm also assuming he did a skin scrape for mites...it's weird
because most "night pluckers" end up being because of mites,because
mites are active at night.They also start on the legs.
So basically you have to consider,is this treatment actually going
to help,personally in alot of cases I think the meds are used as a
stop-gap,and don't actually help the problem.Much like the
cone,sure,the bird quits plucking while wearing it,but usually
about the time the cone comes off so do the feathers.
I was asked if I thought about medicating Beaker,she breaks my
heart sometimes when she gets on a bender,but in her case I do not
think it would help at all,she's not a nervous bird at
all.Chamomile had no effect on her.(She and the other 2 are
currently bopping along to Don Maclean's "American Pie",tone-
deaf,the lot of them)
It may be that since your bird responded to the chamomile,he
thinks the prozac will help.It's a tough decision,and
ultimately,you know what's best for your birdie.
