This is my 8 month old RIR girl Hei Hei. She had what I thought was a bout of vent gleet about 2 or 3 months ago that cleared up within a week so I'm not sure if its related but thought it was worth mentioning. I've noticed the last few weeks her comb has been looking more and more sad almost like its shriveling up. Today when I went into the run to give them some scratch after our really cold night I noticed her face feathers look a bit sparse and a bit white. Are these new feathers on her face? What could be going on with her? I attached a current picture and also a picture of her from the end of October. Some other things that could be related or could not since I dont know who the culprit is, the droppings I am finding in the coop and run are GIGANTIC...like, shockingly large lol. Also, I have found 2 eggs in the last week that have been dropped from the roost onto the droppings board that seem to be thin shelled eggs but its hard to tell because they cracked upon landing and then froze. Idk what that could be about. I feed them dumor organic layer crumbles, they have sand and oyster shells in the run, I give them scratch a couple times a week before or after a super cold night, I use a heated waterer and I refill with fresh E/O morning but I also give them fresh warm water after super cold nights. Hope thats enough info! Thank you for your help!
