I adopted a flock of chickens that had 7 hens. On mothers days the previous owners hatched 4 more chicks. We eventually put down 1 and gave an older hen away. About 3 weeks ago we added 5 more older hens to the flock. WE have a total of 14 hens now. We are having a egg production problem. I think it is because of stress of adding the 5 new egg laying leghorns. But my bigger question with this many chickens how much food should I now be feeding all this chickens. I do have 2 self feeding tubes (man made PVC pipes about 6' tall) in the run and a 35 lbs. self feeder in the coop. These have scratch in them and are not empty. I feed my chickens after work around 4:30-5pm when I collect the eggs. When I do feed them I also give them table scrapes from the night before. This varies in the amount each day. Also on the weekends I let them out of the coop for free range all day. I hope this helps and I hope that you folks can help.
