About six weeks ago, I posted about one of my 6 month Barred Rock pullets suddenly started limping and then went semi-paralyzed. She remained alert, eating and drinking but would not stand or walk. She was laying eggs so I was trying to give her time to recover. She had recovered to the point of being able to stand up but she would not walk. I think she had a stroke. I know several people said Marek's but she didn't show symptoms classic to MD. I finally made the decision to humanely end her suffering - her comb had fallen over - I don't know if that means anything but I have been reading her on BYC and really appreciate the perspective of more experienced poultry people who support culling birds that don't meet the standards. I have 26 new chicks that are a week old and 8 five week old Light Brahmas. Thanks to everyone here - I really can't say enough how helpful and enlightening about the chicken hobby this board has been to me in just two months.
