Making chicken sick with sour crop

Hello

I think one of my chickens has sour crop shes not eating much and has only drunk a little bit of water, her crop feels quite squidgy but its not too enlarged (possibly as shes only had water in the last day or so), I can still feel the grit in there.  We have had a chicken with sour crop before which was much worse, and we tipped her up and managed make her sick and to get it all out over a couple of days and she was right as rain after that, but we cant seem to make this chicken sick which makes me wonder if it is sour crop? 

Can you make a chicken sick if its not got sour crop so is the fact nothings coming out mean its maybe not that, or is it just that we aren't having much luck making her sick?

Don't want to keep trying to make her sick if its not going to happen, she doesn't seem to be bothered about being tipped up where as the other chicken we had, had liquid coming out the minute we tipped her up, there seems to be no reaction at all with this chicken.

She is 2 years old her egg laying is very random she was broody a few weeks ago so her eggs have been very weird if she has laid them.

thanks for any advice

Hi there, thanks for your reply.  Not sure what the problem was but after a day she was right as rain again and went a bit broody but back to her usual self fortunately.  At least we will know for next time and not keep trying to tip her up, she was very patient about it though bless her.
