I got a barred plymouth rock hen a couple of weeks ago and I can feel her breastbone easily. I have other gamey mutt pullets that feel more meaty than this hen, so I'm a bit concerned. The barred rock, Spaghetti, lays an egg every other day, and she does eat some of the lay pellets I always have available for my chickens, and she spends a lot of time foraging in our backyard, eating grass and whatever bug she can find. I don't know what her living conditions were before I got her, but I can tell she didn't eat that well. Spaghetti drinks lot of water and she poops a lot, however I haven't seen anything abnormal in her poop, except that isn't as solid as my other chickens, but it isn't diarrhea. By the amount of poop I see under her perch and throughout the day I know she's eating, but I'd like to give her more stuff to help her gain weight. I've given her and the flock some zucchini lately, and also grapes and sunflower seeds besides scratch in the morning and the ever present lay pellets. I've also given her cheese and some ham, and also bread a few times. What else can I give her to supplement her diet?
