Hello! I have a 8 month old Isa Brown hen. For the past couple days she has been sticking to her coop (my flock free ranges) and she hasn’t been walking properly. She is still eating, drinking and laying eggs. She is hunched over and her wings are not hanging typically, you can see the bottom feathers that are typically tucked up. I gave her a straight dose of vitamins yesterday and today. She has not been getting up on the roost and is sleeping on the coop floor. When I open the gate to their pen she will walk out and even try to run but she stumbles over uneven surfaces and has not been flying out. We have an area that has 3 ft high fencing and they fly out of everyday. I have 4 other hens and a rooster that are all acting normal. She’s alert and eyes are clear. I’ve tried to determine if it’s one side more than the other but I can not tell. This is my first flock so I’m not sure what to look for. I’ve attached a pic of her stance, this is the posture she has while walking, I haven’t seen her stand fully upright in a couple of days
. Any suggestions would be appreciated! Thank you!! Heather
