I find myself groping chickens nowYes I know. It was Shad who ages ago explained that you needed to be firm, and then I thought about what the massage is doing - it isn't a muscle relaxation aid, or a way of increasing blood circulation, it is really physically breaking up the blockage and pushing the crop contents through to the next stage of the GI tract. That gave me courage.
The concern I always have is not pushing stuff too high up so there is a risk of aspiration.

Not sure what they think I am doing, but they sure give me the stink eye! Haha!
