I have a 6 month old pullet with a strange backstory. So she hatched from my two Easter Eggers and was always quite small for her age. When she was 3.5 months old, her feet got severe frost bite and she lost all her toes. She has lived in our house since but has been showing weird symptoms since she’s been inside. -she is very pale (although she has no external parasites whatsoever) -her crop is always a little soft (although she has no other symptoms of sour crop) -her feathers are in bad shape. She has some bald patches, especially on her face where the skin is also very dry and flaky, and all the feathers on her head are sort of crusty and flaky and they break off. Just generally a lack of structure in her feathers and not shiny. She eats normally, poops normally and seems to act normally. She just has these seemingly random symptoms. Please let me know if anyone has any ideas of what this might be?
