Stop with all the treat foods and feed a good quality non-medicated chick starter. Like any kids they will eat the candy and sweets before eating the nutritional foods. If you do persist with other food stuffs be sure to also give grit so they can process the food. Toss the All in One in the trash along with the corrid. All in One products are meant for pigeons and is not effective for peafowl. Giving all the different meds when only one type is needed and especially in too low of doses is harmful. Corrid is not effective for peachicks and starves the chick of vitamins it needs for development. Corrid only blocks the intake of vitamin B that the protozoan needs but also starves the chick. The best treatment for cocci is Toltrazuril, we treat our chicks monthly until mid winter. Toltrazuril actually kills cocci not just starve it so it is very effective. If you have other questions about peas I live in the Peafowl forum and you can post there for faster replies.
