For the very first time, I am raising some chicks, and I've done a lot of reading (boy, the BYC learning center was helpful!), but I want to make sure I have this down.... Treats can be fed to chicks at around one week old (yogurt, eggs, no greens, right?) If fed treats at that age, I know I should feed them grit. Will pet bird grit (like parakeet grit) be ok? Should this be free choice or limited? I need to feed the chicks chick crumbles/starter until they reach about two months of age (the 'Raising chicks 101' article made it sound like I'm supposed to give them layer feed after two months, right? Or first egg? If the latter is true, does that mean even if they haven't started laying at eight months then I should still be feeding them chick starter?) Thanks in advance!
