There was a gal on the local FB poultry group who had a "sick" chicken that she asked the group for advice on. Not receiving the asked-for advice as quickly as she would like she took her hen into a vet. $300 or so later, her hen was diagnosed with an "unknown issue of the reproductive tract". The hen's symptoms were: staying in the nest box, elevated temperature, passing large foul stools when removed from the nest, not laying, and missing feathers on the breast. The general consensus among the knowledgeable chicken owners was that $300 is a lot of money to pay for a perfectly healthy broody hen.My husband gets phone calls to see if he is willing to see chickens, but very few people are willing to pay for a vet to see their chicken.
