I'm so worried for my chickens!!! I'm scared I might lose my flock and I have no idea where to start to try and prevent another death! I hope someone knows what's going on and can give me some advice. 3 have died. ....The first one died when she was about 2 months old (this was a little over a month ago). ....The second died about 1 week ago. ....I found the third one dead today. Some "clues": -One of them was making a weird sound...I suspect this was the 2nd one to die, long after making this sound: -The ones that died happened to be bought from the same lady (as hatching eggs) -They were all sudden deaths (noticed odd behavior day before or of death -No diarrhea -Lethargic -1st chicken to die seemed to be getting progressively weaker/slower walking -2nd chicken to die had balance issues...stumbled when trying to walk -3rd chicken to die...I wasn't home yesterday or today to notice signs (hubby took care of them and wouldn't notice if anything was off) My husband put fertilizer down over the grass a few weeks ago. We kept the chickens in for a while until it dissolved (we had a bunch of rain which helped). Even if they managed to find some would it kill them? Any thoughts would be very much appreciated. Or a good website on "diagnosing" chicken illnesses.
