I really like this feeder. I bought this to use for my chicks. I ended up using it up until they were about three months old. Then I got a bigger feeder. When they went into lay, I used this as on oyster shell feeder. I am actually surprised how long it lasts. It was only about $5 so I wasn't expecting it to last very long. Mine is about 2 years old and still in use. The only problem I have with it is sometimes after I fill it, the bottom falls off. After about the third or fourth time this has happened, I started to get annoyed. But overall, this is a very good feeder.
