Dazed Pigeon with drooping head

[Jules]

I am going to pray that it's not a sour crop. I know that doing that procedure would scare the life out of me.
I do check his crop when feeding him and it "seems" to empty. Also, when I give him water, it is warm and I do sort of massage his crop. He is pooping and it's quite firm.
Some questions:
should I give him the spartrix before feeding him?
how long do I wait till I feed him?
should be one pill a day for three days, correct?

the parasites, how do I treat for that?

thank you

Oh.... doh... I should mention that he has been holding his head up for the last twenty four hours (Yeah! )

On another note... I am going to try and order meds from Siegels to have available when I need. What's a good basic order to treat most ailments?

thanks again (trying so hard not to be a pest)
