Hello everyone, I have a young Black Sex-Link hen that has just recently started laying. I noticed her holding her wings out to the sides slightly last week a couple of times but thought perhaps she was cooling herself in our unusually hot winter here in Florida. Last night I noticed her doing it again on the roosting pole, so I picked her up and was shocked to feel her breast bone!! She has definitely lost weight. Her appetite seems normal, she acts normal, foraging and chasing bugs, and loves her treats and an occasional finger...ouch. A bit of a back story...I went to a Farm Swap in January (UGH!! yes, I have learned my lesson...OH! and another valuable lesson: never trust anyone that says, "yeah! stick 'em in there with your chickens at night and they'll be just fine in the morning."...thus exposing everyone to sneezing and wheezing. yay). It was my new rooster that showed signs of wheezing and sneezing first. I isolated him for 10 days and administered antibiotics (Tetroxy) starting on Feb 2nd. He showed some improvement and then I had 5 hens start sneezing. So Tetroxy for everyone! Everyone seems healthy...a few occasional sneezes from the rooster. The only wheezing I hear is from my rooster, when I have to chase him around 4 acres to put him up earlier than he thinks he should go in. I am using Bragg's ACV in their water. Epsom salts in their pellets. Butter milk or yogurt, spinach or romaine lettuce, oatmeal, brown or white rice, strawberries, apples or grapes, and wheat bran mash at night. Seven Dust and Diamatious Earth in the coup and in their dust bathing areas. I have not wormed yet. Any recommendations would be appreciated. Thank you everyone for any help you can offer!!
