I have poultry vitamin powder? It's still giving the occasional peep. Hasn't fluffed up either the feathers are rock hard especially round the head.
Try dissolving a little in some warm water and give a couple drops of that... sounds like it was sticky gooey when it hatched, that stuff dries rock hard... once it's mobile you can gently soak and wash it off in very warm water, just keep it's bill out of the water... gentle towel dry and blow dry on low setting to keep it from getting chilled...
