I got an assorted batch of day olds on March 10th. 2 silver grey dorklings, 2 americana, 1 buckeye, 1 sultan. The dorklings have been bigger than my 2 year old barred rock for about a month and the americanas are the same size. I've search the yard over and over at different times of day and all the bushes are pruned back so I can get a good look under. The feed schedule and type for these "chicks" has been the same as for the last set of birds I raised, (buff Orphington and barred). Those were laying at the start of 5 months and they were smaller at the time. Any body have some thoughts? I'm thinking about sticking a red light in the coop to start extending daylight hours. Thanks, Eric in Colorado.
