Hello, several of my chickens that were hatched around April are losing feathers on there necks very slowly, on another sight it said it was a small molt. They have been growing there feathers back and it's not been a big deal Then today I went into my coop and found this. It has had to of happened over the last two days. Yesterday when I went out it was dark so I don't know if it happened yesterday our today. She had been acting normal. I have no idea what it is and any help would be greatly appreciated! Thank you!
