I am giving 3 of my birds penicillin, I have some infections I believe due to stinging nettle,one has a swollen and now blackend ear lobe the other s have swollen feet and rough skin ontop of their feet, andy how my question is does any one know if I can reuse the needles on thees birds after bleaching them???I have used a clean needle for each bird as I did not want to insert dirty needle into penicillin bottle if I use new needle for each bird for 4 days that is a lot of needles, ....OK will do if bleach is not a good idea
