Lethargic Hen, need help please

[PookiesChicks]

I have a buff Orpington chicken who is 4 months old. She has been lethargic since yesterday morning but is worse today. Today she won't eat or drink and has not left the coop. The temperatures have been in the low to mid 20s the past two nights. Our other chickens are fine and active. I put a heat lamp in the coop today to warm her up but it hasn't helped her. What do I do?

Is she standing or walking at all? Had she lost weight? How do her poops look?

If she is still not eating or drinking I would bring her inside to a comfy spot and try to feed her and definitely try to make her drink something. If you have any sav-a-chick electrolyte packets try to get her to drink that to make sure she is hydrated.

Can you say any more about how she is acting?
