Hello, I am very new to raising chicken but I am in an urgent need of help! One of my very first hatchers is very slack and lost a lot of weight. When we got them at the beginning of this summer, she was really round and active. We were told that they are young chicken also. I have never hold her before, but I think that this weight she has right now is abnormal. She is super skinny also Feathers do look good tho! She does follow others when they get outside but when I give them food, she just stands in front of it and doesnt eat. She wont go up on the perch and she just stands in the corner, alone, not with the others. She tries to sleep and is like tapered together (my english is not really good, sorry) I have no idea what to do now. I think that maybe she has a cold? I do keep them outside sometimes when it is sunny and not windy (we have about 0 degrees now) At night they are back in the shed. Maybe she got some wind and is feverish now? Is there anything I can do? Bring her inside to get warm, feed something different? Thank you for any help!
