Well if that continues, then you may need to cage Henneth so she can eat/drink in peace. Cryss, what do you feed? While it's not that unusual for a chicken to molt "early". I do wonder about Henneth molting at just 41weeks. There are no absolutes in the chicken world, but "most" birds go through an annual molt at 16-18 months of age.So this morning there are 3 each of food and water stations. Henneth had to be encouraged to come out. It didn't last long. The other Barred Rock, Petra, decided to attack and chase her so she ran back in. We shall see how the day unfolds.
Have you looked at Henneth to see if she has new pin feathers coming in and she is not being plucked?
