adding new chickens.

[winnman]

All right my first chickens were born in march of this year. they were all laying one egg a day begining in Augest now one she hurt her leg and has stopped laying plus one more has stopped. Someone said I should add a light so I did, because the days are becoming shorter. Other say they are molting all ready. A friend of mine gave me two Cochrins that are one month younger, they are great looking chickens they have only layed one egg , but when I try putting them in with the first six they try to kill them
