I have one Buff Orpington and one Black Australorp both are supposed to be hens. They are approximately 3-4 months old, sorry, I did not note the day I got them but am thinking at least 3.5 months. The Buff Orpington has the most noticeable symptoms which are: The comb has started to come up but after 1.5 to 2 weeks, has stopped developing at all, same with the black. All facial areas, around the eyes, beak and ears is red, very red. Both are eating good and do not seem to feel bad tho the Buff sometimes seems tired or confused but is hard to tell for sure. Wish I could ask them where it hurts! Trying to attach a picture. If anyone can tell me what to do for this I would be very happy! I do not want my girls to suffer. Thanks for the suggestions!.
