yesterday i went down to the flock, and i noticed that this one chicken couldnt get up. i took her out of the nest, and put her on the ground and she struggled to move a foot. i brought her to the waterer and she did drink, and she also ate out of my hand. i seperated her last night, and she did lay an egg at some point last night and this morning. i gave her water and food this morning, but she still was very weak and could stand for more than a couple seconds and laid back down. she is only coming up on a year old now. anyone have any idea what could be wrong?
