I hope the injections went well and your hen got better. You were brave to take on giving Penicillin injections.

Those are hard. I haven't liked when I've had to give Penicillin injections to birds, but it sometimes is such a big help.
If it's useful to anyone in the future, I've put together some suggestions on giving Penicillin injections to birds at

You can also give Penicillin (or Amoxicillin instead) via pieces of pill tablets or soluble powder from pill capsules.[/COLOR] You can use pills that are for people, or order pills from
TwinCityPoultrySupplies.com or
