I have 4 hens. They have all of a stuff on stopped eating their layer crumble. They will still eat their favorites, but they are not fans of their food all of a sudden. It has been unusually cold here in California recently, can the cold make them stop eating their crumble?? I give them Kings layer crumble. They seemed to be enjoying it up until recently. They have been wormed, they are due again the end of January, combs red, no discharge. 2 of them havnt laid in a month and the other 2 just recently stopped laying. Any body ever have this problem?? They get a handful of scratch in the morning, and normally they inhale it. These past couple of days they have finished it off. Like I said it has been really cold here...well cold for California.
