I think 2 of my hens are under weight. I can feel there breast bone a little. When I get home from school I usually throw down some mash so they can scratch at it. Well I reconize the 2 just kind of sit back and wait till everyones done, then they take whatevers left. I felt them and they feel under weight. So I pulled out my hanging feeder, And everyday I fill it to the top, So they are alway have food next to them. Do you think they will gain weight, if they have that feeder there with food in it always? its 10:40 at night and its half full, and tommorrow at 3:30 After school Ill fill it.
