How do I choose the best waterer for goats and sheep?

I was sitting at home and thinking about farm work again because my cousin was talking about automatic poultry feeders and he said feeding animals on time is very important and I start wondering if these machines really make life easier or just sound fancy online

I checked alibaba while scrolling on my phone and searched best automatic feeders for poultry farms and I saw many options like gravity feeders timed electric feeders smart sensor feeders and large capacity farm feeders some looked very simple with basic storage tank while others had digital controls and portion settings and I also noticed reviews saying automatic feeders save time but sometimes jam if feed quality is not good and I is trying to understand which type farmers actually trust for daily use

Now I feel feeders are not just machines but part of daily farm routine because if feeding system fails even one day it can affect animals health and I dont want to choose something only based on features without knowing real world performance and I think maintenance and feed type also matters a lot and people online say simple designs are more reilable for small farms but advanced ones look more comfertable for saving time and I keep thinking which balance is better for long term use

Do you think automatic feeders are really better than manual feeding for small farms?
