The whole grain feed is not good. You are giving your birds the option to pick and choose what grain they want or don't want to eat which causes problems. I highly recommend you feed a crumble or pelleted feed ONLY.It’s whole grain feed and store bought layer feed. The cucumbers were to hopefully help cool them since it was 88° here in Florida but they didn’t like them so I tossed them.
You have the ability to prevent your birds from suffering by what you choose to feed. Birds who don't get a balanced diet are highly likely to end up with irreversible issues that could have been prevented by diet alone.
