I just got 2 hens from a neighbor. They are both about 2 years old. Have been fed only corn their entire lives with no calcium supplements. They did live uncaged in a small yard. We examined them and found their breast bones stick out about 2 inches if you put your hands into the feathers. They have very little muscle over their bodies. They have to stop for rest breaks and breath hard just going up the ramp into the hen house. They do go out and walk ocassionally in our yard but mostly stay in the run and they get tired fast. The poop looks normal no blood or worms seen but they do have droppings stuck to the fluff around their vents but they have been sleeping on the floor of a dog kennel on top of a huge hardened pile of poop. Vents are clean. No parasites seen in feathers or on vents. We have had them for 2 days. Day one the RIR laid a regular egg and the Amerucauna laid an egg with no shell just membrane. Day 2 neither one laid an egg. The RIR has a rather large comb and one portion of it is cool to the touch and that part is not blue but a bluish red color the rest of the comb is normal warm and bright red. The RIR's feathers are very dark brown instead of red brown and both have mostly dull feathers. The Amerucauna has a few patches of downy showing through her back feathers. No discharge from their noses. Eyes bright and clear with red/orange eye color. Feathers are not loose. What should I do to get these two ladies healthy?
