What did he farm the ostriches for, eggs?

I grew up on a farm and there was a family in our area and they used to have peacocksz but I’m pretty sure they were just there the visual interest because I don’t think they were actually part of the farm stock. I always assumed that people kept ostriches for pretty much the same reason, because honestly they are pain to deal with. I certainly don’t think I’ve ever really seen ostrich eggs being particularly high in demand.
