...and I hate to be breed biased, but the 2 wynadottes I have are the meanest birds in the flock.
Chickens do go thru 3-4 mini molts before one year of age.
The new pin feathers are full of blood and bleed easily if pecked or broken.
I have a batch right now about 11 weeks old and their coop is full of feathers and they are showing new and different plumage.
I'd up their protein and give them more space.
