Power feeding means that you are feeding an increased amount of proteins and fats to get quick growth, bypassing the other portion of the diet which offer more of a balance of vitamins and minerals. The problem when people power feed varies on the species. With chahouas it can lead to MBD, calcium crashing, and vitamin deficiencies. The thing about chahouas as say compared to cresteds, they require more protein anyways. Power feeding is normally done to try and grow up faster to breed, chahouas actually grow rather quickly when fed correctly, the problem with them is egg laying takes a lot of them which is why it is recommended to wait until they are older instead of going by weight. The idea of power feeding comes more from the crested community which more people focus on weight rather than age so they will try and bulk them up quickly to 45g so they are considered breedable.
