I have a 6-7 month old RIR/NEW Hampshire cross. She has been sneezing since I got her 3 months ago. Away from other hens for 3 days while ran antibiotics through entire flock. No signs of sickness. Just sneezing. Flock does not show sneezing. It's been 100 degrees and up for about a month here in TX. Is this just allergies or crazy hen? No mucus or eye infection. Still eating, laying and drinking. ?????
