Excess heat, cold or damp can have a harmful effect on the animals and their productivity. [15] Free range farmers have less control than farmers using cages in what food their chickens eat, which can lead to unreliable productivity, [16] though supplementary feeding reduces this uncertainty. In some farms, the manure from free range poultry ...
RSPCA standards state that in order for chickens to be free range, there must not be more than 13 chickens per square meter.

However, for boneless, skinless chicken breast, the amount is much lower. 100 grams (3.5 oz) of raw chicken breast contains 2 grams (0.071 oz) of fat and 22 grams (0.78 oz) of protein, compared to 9 grams (0.32 oz) of fat and 20 grams (0.71 oz) of protein for the same portion of raw beef flank steak.
Morning: Let chickens out of their coop, giving access to the enclosed run. Give each a quick once-over, looking for bright eyes, red comb and wattles, steady gait, and shiny feathers—all signs ...
