I have 6 ladies, 5 2yrs and younger, 1 who is about 4-5 yrs old. The older lady hasn't laid eggs in about a year. she has been having trouble walking for the last few days. She can take a few steps and then collapses. She has poop all down her bottom (for awhile now). She is hunched over, tail tucked, shoulders up. When she sits down it looks like she is on her side and uses her wings to balance. She has trouble going up the ramp to get into the coop so we pick her up and put her in, but now she has trouble coming down the ramp. And she stinks, none of our ladies have ever smelled! One of our 1 yr olds is starting to exhibit some of the same symptoms. The 1 yr old hasn't laid an egg for about 5 days. She isn't usually a daily layer, but does not go this long between eggs. She doesn't have a tucked tail or hunched shoulders, a little poop on her bottom and trouble walking, again using the wing outstretched to balance. thanks for any help!!!
