Hi, new to the forum... I currently have a flock of 11 chickens (10 hens/1 Rooster) We raise a mixed flock and all have been together since their arrival from the hatchery 18 months ago. We do add light during the winter and have plenty of space in coop with four 4' roosting bars. A couple of issues have come up in the past . #1. Pretty significant reduction in number of eggs weekly. We were getting 40-50 a week now getting less 20. It is winter here in SC but as I said they are getting 14 hrs of light each day. Last winter they were laying well with not drop-off in production. We have fed Dumor Layer Pellets throughout. #2. 5 of the hens have stopped roosting for the past few months. They sleep on the floor and 3 of them are Creme Legbars and they are lower in the pecking order but still laying at a good rate. The only major changes is that the dominant rooster (Speckled Sussex) got a respiratory infection in May (treated with LA-200) now recovered. During his quarantine my 2nd rooster a Salmon Faverolle took over. Then, I did lose the Salmon Faverolle the end of August. Watching for mites (haven't seen any) but curious if both issues might be social in nature. Did losing a rooster trigger a social dynamic affecting both egg drop and lack of roosting? Or is it something else?
