Yes, that is enough. Penicillin dosage here on BYC is all over the place. There is a wide safety margin, but the smaller amount you inject, the better in a chicken"s breast. If you read one link, it says 1/2 cc, another says it is 1/10 of a cc. Here is a post from Natalie Ross:I found this information by SpeckledHills also for anyone who is having similar issues https://sites.google.com/a/poultryp...oultry-podiatry#chickens_penicillin_injection
This person is very extensive about how to administer shots in general along with other issues that one may experience.
Eggcessive, 0.1 ml? really that's all. That seems like such a small dosage. Or is it 0.1 ml/ pound?
Pen G procaine is given daily for no more than four days. The dosage for poultry or waterfowl (under 10 pounds) is listed as less than 1/4 cc if the Penicillin G Procaine is 300,000 I.U. (which is most often is) for animals from 1-10 kg (each kg = 2 pounds, so 1-20 pounds). The dosage is actually listed as 1ml (cc) per 100 pounds of body weight, but giving 1/10th of a cc would be troublesome and it has a high safety margin.
