Relatively cold days and nights in GA. 8 hens don't appear to be eating what I would expect (My first winter) I am leaving a feeder full of layer pellets... available 24-7. They free range all day; come in coop at night to roost. I generally feeD the 8 hens and 4 Guinness a solo cup of scratch a day. My guess they are eating no more than 1/2 cup of layer pellets a day. I am getting 4 eggs a day from the 8 hens... I assume they are getting more food free ranging than I would expect to be available this time of year, Any concerns?
