An estimated two million laying hens have been culled in South Africa since the H5N8 avian influenza outbreak about three months ago. Around 50 cases have been reported at commercial chicken and ostrich farms, along with cases in wild birds and backyard flocks.
Large-scale layer culling reduces egg supply and feed demand from the layer sector. Lower feed use in South Africa is mildly bearish for local maize and soy meal, while the egg shortage supports egg prices.
