So I have a brown leghorn chicken she is about 4 months old and for the past two weeks her crop has expanded to about half her side. She is majorly too heavy and I have removed her from the other chicken and she's in her own own inside my house. I have tried to give her apple cider vinegar water and yogurt as the vet recommended. She also said that it could be a blockage but her crop has not gone down and she has thrown up food which is unusual and she can no longer move and she falls to the left and scoots herself to where she can get comfortable in her pen. She wants to snuggle and sleep all the time and she can barely keep her eyes open, she's not eating I dont know what to do I dont want her to starve to death. She is also half the size of the other two brown leghorns I have that were gotten at the same time...HELP!!!
