. Are his poos back to normal and everything? He seems better? If yes, he might just be telling you that he prefers the real food to kibble (and who can blame him). You could mix a little chicken in realllly good w/ his kibble to make it more enticing. If the chicken portion is LESS than 15-20% of the total meal, then you don't have to really worry about throwing the supplement (and cal-phos ratio) balance out of ratio. If you homecook permanently, then you need balance.
Long term, you could consider adding canned food (ie, Evangers) so he has variety, more moisture, less processed meat, more exciting food. Nothing wrong w/ that.
