I have two chicks. Probably four months old. Swedish black hens. Two days ago one was clearly not feeling well. Yesterday she stayed with her sister, slowly, and her sister called her to the coop for the night and they went to bed together and everything. Today when we got home we couldn’t find her and she was under the shed. After pushing her out I was able to hold her for the first time as she was so weak. I assumed she hadn’t been drinking water so I gave her some through a straw, because she wasn’t drinking even when I held some to her beak. When she tried to walk away, she was very limp and staggering around. I figured she might be too hot and put her in shallow water covering her feet. Which were super hot. (It got to 90 today) Now she’s laying inside my car with the ac on. Eyes closed breathing heavy. She has had some watery poop which has left a small amount of white near her rear. And in the car on cardboard I could easily see it is very bright green and watery. Do I need to research Illnesses or could it just be the warm summer days getting to her? These are my first girls and I didn’t realize how hard it would be to see one sick. Any input helps and is much appreciated. I’ll refresh this thread religiously as I try to help this girl through the night. Thank you.
