Update: I dont have a feeder, we are planning to get one as soon as possible. However, today when I went to feed the chickens, I planned to feed in bowls. The thing is that when I went to do my morning check on their sacs, some had full sacks from yesterday. I decided to trap them in the coop with no food and water. They have been in there since 7:00am, should I let them out to have only a water source? Their water is located outside, so they will also be able to have a few food sources including grass, bugs, etc. I am suspecting sour crop, although I feel like they may just had too little time to digest everything (all 15 cups from yesterday's dinner fed at around 6:30-7:00pm)
