Well, usually, I give a bigger bird like a rooster or a huge Orp hen 2 baby aspirin the first go-round and one the next day then I stop for a few days and continue if it seems necessary. A less heavy hen will get one 81 mg. every time. But, in that mixture, I crushed three 326 mg regular aspirin and stirred it around so no way to know who got what. I figured Atlas would get some, but I don't think he touched it at all. He's better when I pick him up, but he protests more when Tom does. He's a big mama's boy. I admit, I take advantage of having to treat him to cuddle him and talk in his ear a little, tell him how good he is. He seems to enjoy that, or at least, he tolerates my attentions, LOL.
Thanks for dosage advice Cyn. I will make a note of it and put it in my medicine box. Good to hear that Dottie is back with Atlas' flock!
