How old?

[Wyorp Rock]

Her ear lobes are red in colour.By clumsy i meant she has a round stout body and is very slow in running. May that is a sign of a old hen.She doesn't have any illness now. But when i bought her she had mild fowl pox.Now around 2 weeks after recovering. Egg production is very low now(Don't know if it's because of the disease). Eggs were bigger than a pullet egg but a little smaller than the store bought commericial eggs.Everything else is fine and she eats quite heavily.

She may be overweight, that can cause some problems with production. Try limiting high carb foods (bread, rice, pasta, corn, etc.) and add more protein to her diet. If you don't use commercial poultry feed you give a little fish or meat daily.
