So I have not seen this before so bad 1 hen is having a REAL HARD molt, ok no biggie. But it is Super chilly here (Teens over night, 30's daytime). On her back and a section on her side is a big swath of no feathers and Pin feathers coming out. About 1.5-2" long pointy. My issue is that the ends are Not opening up like they have done before. They are pointy. Now maybe it is just that it is such a wide open area, with no other feathers covering it, that it is more noticeable. I am sure this is it but I am a bit concerned about the cold weather. They are dry and happy, eating & drinking. No one fighting as they all (but the low totem pole girl) are molting. They are getting Feather fixer for the past almost month, mixed with their Layer. Flock block cracked up & cracked corn everywhere in the covered run every 3 to 5 days for them to shift and peck for in the straw. I am going to give some warmed up wet cat food (cat won't eat it) as a treat tonight for all. At what length of Pin Feathers should I get worried if they are still not opening at the end ? Watch, I will go out there now and the end will be opening making me look like an idiot.... they seem to like to do that to me.
