Similar situation!
When the hens started to molt this year, as normal the egg production slowed dramatically. The problem is that we have 2 - 3 year old Easter Eggers, 1 -2 years old Buff and 1 -2 year old Cuckoo Maran. We did have another Buff but at some point during the molt, she was attached and would up dying a week later. They really beat her up. Every since that time we have had no eggs. Still a lot of feathers everywhere as they are not molting at the same time.
The funny thing is that during the summer, the then 2 Buff and the Cuckoo were laying like champions, which prompted the the Easter Eggers to start again after not laying for 6 months.
Everything we OK til the molt then its zero eggs and crazy birds. They have plenty of coop space and a 15 X 4 run that is well protected.
