Hey Gang! I have a leghorn who is 10 months old and has had a slow health decline. Her comb has never developed like the other girls and in the past couple weeks she has started isolating herself from the flock of the other 20 hens and one roo. I have had her isolated for 4 days and started Tyvek then as well. I started calling her Janice because she looks jaundice on her legs and beak.... she is a lot yellower than the other leghorns bought at the same time. Her wings are droopy. She has great interest in the scrambled eggs, grapes, and meal worms I give her. I added vitamins to her H2O. There is a heat lamp in a barn stall with her but she is choosing to hang in a cold dark corner. She has not laid any eggs since she has been in isolation. Tonight when I gave her the abx she was easily tipped over on her side with no resistance and then after administration I was able to palpate her abdomen which was quite firm. Her breastbone is very protruded. Her poops are very small and dark. Is it possible she has just had a poor immune system and failure to thrive so to speak? The lack of egg production is alarming I think?! Any help would be appreciated! TIA!!!
