I rescued 2 chickens about a month ago. One of them started becoming inactive about 5 days ago. I thought it was because she was about to lay her 1st egg. She has laid one every day for the past 3 days. About that time I noticed she doesn't want to come out of the chicken run when I open the gate. She was eating and drinking very little. Not walking much and laying around in the run. This morning she wouldn't even come out of the nesting box. I picked her up and her comb is not standing up and she kept closing her eyes. She just lays in my lap. Tried getting her to drink some water or eat a grape but she wasn't interested. Just laid on my lap with her eyes closed. I put her back in the chicken coop next to the food & water and she hasn't moved. Please give me some advise on what could be wrong and what I can do. Don't want to lose my Betsie!
