Have taken some latebreds this year ( never usually ) So anyway, getting my father to get them out over the winter, (they only get fed once a day ) There is 10 of them and they have been disappearing with some ferril doos away to the fields, coming back after about 2/3 hours in ones and twos full of whatever they are eating in the fields , is there anything I can do appart from feed them more? They get grit and natural pick blocks , never experienced this in all the years I've kept pigeons , Any advice welcome
