we have 5 chicks almost 8 weeks old. How long can I feed them the "baby food"???? As far as I can tell, it seems similar to the other food just crackled up and higher in protein....I thought they would eat alot more than they did and now that they are outside they eat very little feed at all - getting their fill from the forest. they are not free range but we have a 20 x 34 run so each chicken has over a 100sqft of personal outdoor run space. I doubt the free food will last forever but it is an old dog run in forest been unkept for a good 20 years,...so lots a forest debris, critters and what not for them to sift through.
