I probably give them far too much to eat, as there is always food they haven't gotten to yet. I have four hanging feeders with just commercial stuff. I want to be sure that even those low in the pecking order get enough.
Their litter in the henhouse is strewn with grains and seed, which they love to dig up. The chicken run is strewn with kitchen scraps, grains, seeds and fruit (mainly apples). I gave them huge pumpkins, but they were not too fond of them. Tomatoes are probably the favourite.
Chickens love greens. Clover, dandelion and salads disappear immediately. Of course,nothing stays alive in their run as it is eaten up, but I bring them cuttings.
Now that the temperatures are around 10'F I bring them two hot meals: porridge, potatoes, pasta. They love youghurt but I rarely have milk as I would have to buy it from the shop.
The flock is 28 and freezing temperatures mean they need energy. I give them fatty winterbird feeder balls which are actually meant for small birds.
My chickens are not fat, but surely nobody stays thin either! It is quite endearing to watch how much they love eating. Especially if you throw the food around and they get to dig it up.
My definition of a happy flock is that you see lots of tails as they are pottering around π
