I have just two hens; a goldline and a Rhode rock. Both have always been in good condition but it is starting to worry me that every morning my goldline will take a few bites then go about her business but the Rhode will be pecking away for a long time afterwards. She also drinks much more water. She's a lot bigger than her companion and lays sometimes two eggs a day whereas the goldline generally sticks to one but the difference in appetite is immense. Is this a problem?
