Chickens turn to peck at their flock mates in search of calcium, protein and such. This is a very nasty habit that can occur in the flock so it is very important that the first culprit be separated from the flock and put in a separate box. With changes in the diet the chicken keeper can make sure that the rest of the flock don’t get the same nasty habit and therefore improve their well-being.

4. Lack Of Vitamin A

If your chickens have dry and crusty material around their breathing areas that usually means that there is a deficiency of vitamin A in their system.

    I have been having a problem with a few of my chickens going lame. They start walking like they cant control their legs. When they eat they are off balance. Ages vary from young birds to adult birds. They are fine otherwise. No diarrhea or loss of appetite. I cant find any descriptions of this type of disease. Not all of my birds get it so it must be genetic??
