Pharm I am sorry about your chickens and am hoping you don't have to put down your whole flock.
I ended up with 6 baby chicks from that hatch the 3 eggs that were left were no good I cracked them open and they had black small blobs in them that didn't even come close to resembling a baby chick. Next batch in another bator are pipping and cheeping so should have some more fluffy butts soon. Tried putting some pictures all night of the fluffy butts all dried and fluffy but for some reason it is just not working.
I finally have a Broody hen my Splash Maran who hasn't been laying and I thought might have something wrong with her as she would just stay in the coop on the floor (she usually doesn't go on the roost) unless I booted her out of the coop and closed the door then it dawned on me tonight that she keeps making herself a nice little pile of wood chips and when I checked her chest is plucked so I gave her some of the other girls eggs to hatch and she settled right down on those eggs.
Have an appointment Wednesday to see what happened to the arm that was doing so well until I went to therapy and they pushed too much because they couldn't believe I wasn't in pain so now it is messed up worse than what it was before the surgery.
good luck with your Dr appointment ...I would switch therapists...would not go back to that one ..
