Antonia, have a look at this blog for empirical results. Using his results, the answer appears to be - for 4 lb raw chicken - 2.2 to 2.92 lb of cooked meat. See what you think. Does this help you estimate for meal prep?

That blog post is not particularly relevant. It deals with a *boneless & skinless* cut of one specific part: the chicken breast.
It does not address the weight loss of bones and skin of a whole chicken.
Moreover, the blogger baked his chicken whereas AntoniaJames is poaching hers. There is less weight loss from water evaporation via poaching than baking.
CV found problems in the first source.
See this second source, USDA on cooking yields from various meats and various formats (includes whole chicken, includes poached).

As they say at Oscars time, for your consideration.

It would be wise to underestimate yield and expect to get 2.75 pounds of meat from a 4-lbs. chicken.
