I know you all get a lot of these same questions but I'm hoping for some direction. Yesterday I found one of my RIR laying on the ground in the run. Laying in one of their dig spots. I picked her up and she wouldn't extend her legs. Wherever I placed her she would lay right there. It was obvious something was wrong so I moved her indoors in a dog crate. She will eat and drink when its presented right in front of her and will occasionally stand to drink. Although standing up seems a bit difficult for her to do. I noticed diarrhea in her make shift box as well. Greenish brown it seems. Last night I thought I felt her crop which seemed like a hard knot but I really don't know what I'm doing in regards to that. I plan to check for her being egg bound when I get another set of hands to help. Also her tail feathers droop and she seems a little puffy (feathers) when she stands. Its been 24 hours since I found her laying in the run. SO basically yesterday morning sometime after walking out of the coop she decided to lay down. I thought she might be broody but now I don't think that is the case. She seems alert, eyes are clear and good color in the comb. I don't see any mites but that doesn't mean she doesn't have them. Flock was wormed last year but that doesn't mean anything as well. She has had very little food because I know she didn't get any on her own yesterday and I only gave her a little for fear of her impacted crop. Any ideas?
