I had a friend who told me about chickens that were living in very poor conditions near his work so one day I just stopped by and visited with the people and talked them into selling them to me .I had to give way more money than what they were worth,but after I picked the first chicken up off the muddy roost that was in a coop with no top or protection from the elements it was worth it these chickens has no breast that I felt at all the only thing they had been fed was table scraps according to the owner.So I took 6 scrawny chickens home and put them in a chicken tractor that was about 6ft wide and 8 ft long.I then started feeding them about 6 good handfulls of hen scratch that I poured wheat germ oil on twice a day and kept a feeder full of medicated chick starter by them all the time.The outcome was awesome it took about 2 months for them to start looking normal again but they have made a full recovery and I am now getting good fresh brown eggs. hopefully this info is helpful to you so good luck.
