I have a hen who is approximately 8 months old. She was laying regularly for about 2 weeks and now has completely stopped. I noticed the red on her face, comb and wattles is now a light pink and they have become much smaller. I read that anemia can be caused by lice or mites so I checked everywhere on her and can't find anything. Her skin throughout her body is completely white, I'm new to chickens so I'm not sure if this is normal. Besides looking anemic she is doing okay, eats and drinks normally and still forages around. The only change I've noticed is she opens her beak up and almost like gasps. Doesn't do this all the time but frequently enough that I've noticed. Does anyone have any suggestions on what I should do or could someone point me in the right direction. Thanks!
