I started with 1 RIR Rooster and 5 RIR hens. When the hens started laying I was getting 4 to 5 eggs large tan a day. About 2 months ago, I had the dogs outside when the chickens were free ranging. My dogs have never attacked the chickens before, but they did this day. We lost one chicken in the attack and another hen lost a lot of feathers, but she survived. We read that the attack would probably put them off their laying. So we were down to 4 hens and we were getting 2 to 3 eggs a day about a week after the attack. I figured the one who lost a lot of feathers wouldn't produce for a while. About 3 weeks after the attack, we introduced a Jersey Giant hen and a silkie hen and a silkie rooster to the coop. Everybody seemed to get along fine, but egg production stopped. I read that introducing new chickens to the coop would cause them to stop laying until they got used to each other. The JG was in the laying boxes quite a bit, but we never got a large egg from the boxes. We started getting a small, light tan egg that we assumed was the silkie's since the RIR's eggs had been large and we read that the JG's would be large also. It has now been 5 weeks since we introduced the new JG and silkies to the coop, and we still only get 1 little egg a day. What gives?
