Make sure to use a 22 gauge needle, penicillin is thick, a 25 gauge is too tiny.
Keep it refrigerated and shake well before syringing it out, the good stuff floats to the bottom.

Side note: I'm going to clean the coop really thoroughly again this week and am wondering what is safe? Just Dawn dish soap and warm water? Can I use white vinegar on the glass?
Thankfully then, 22 gauge was the smallest they had!Make sure to use a 22 gauge needle, penicillin is thick, a 25 gauge is too tiny.Keep it refrigerated and shake well before syringing it out, the good stuff floats to the bottom.

Thankfully then, 22 gauge was the smallest they had!Thanks for the info.
This is when it would be really helpful to have a vet to talk to. All of my books suggest that a five pound hen should get 0.76 ml.@casportpony Kathy, I have a bottle of PenG in my fridge. It has the same amount of units per ml, 300,000 as does this Agri Cillin bottle the OP listed. It is also Pen G. I would imagine its the same stuff, same dosage as any other Pen G?
I give .5ml to birds 4 to 7 pounds. I would say a bird twice this size would be .75 to 1ml? Kathy is the expert on exact dosages.![]()
lol, it's just the books.You know more about dosages than I do.![]()
