I have been watching a broody hen forage with her chicks on pretty much a daily basis. They find, capture and consume a wide range of food items. Smaller chicks eat critters almost exclusively if not consuming starter feed applied in morning and evening. The sequence of find, capture and consume is significant in that more is found than consumed and capture is in between in respect to item number. Largest items consumed might be a fledgling bunting, mouse, lizard or small snake but these are not encountered on a regular basis. Froglets are found frequently and as season progresses larger insects, especially grasshoppers are noteworthy. The hen invest considerable effort chasing larger grasshoppers, sometimes more than a 100 feet. Chicks still not capable of catching such grasshoppers if insect warm and healthy. Chicks capture smaller and slower insects on their own. What is obvious is that not all insects I can see as birds forage are engaged by hen or chicks. Either they fail to see such organisms or they pass over them intentionally. Insects coming of milkweed plants seem to be ignored. Most butterflies and some bugs also ignored. I suspect there may be a pattern in respect to what insects are consumed or ignored. It would make for a very interesting and potentially easy to conduct experiment suitable for a science fair project.
