My 1.5 year old White Rock hen is very sick and I can't find anything online to help me figure out what is going on. She did not lay an egg yesterday, last I checked for eggs was 3pm. I checked the coop and found her egg at 10am today. Normal size, coloring, she was acting fine. They're in a tractor and I moved their coop/run, she was running around foraging and being a menace to the others like her usual self. Then at 3pm I went to give them treats and she didn't move at all when she's usually shoving everyone out of the way to get them. I was watching her and she seemed like she was in pain and trying to poo/push an egg out for the 20 min I watched her. I took her out and looked at her vent, it was pink, free of any pests and wasn't prolapsed or anything. I put her down and she moved to forage/eat a little but wasn't moving as fast as usual. I came back to check on her an hour later and she was laying down in a corner, it was like she was depressed [in searching for answers this was a common term used, that's exactly how she seemed]. I put her in a warm bath and she seemed to relax and she was able to poo. I put her in my old brooder and she wouldn't even groom/shake herself off, so I held her in a towel with a heating pad and she passed a soft shell egg. I thought this was why she was struggling/feeling so bad so I put her in the brooder to go to bed but when I checked on her she had passed ANOTHER egg yolk/whites into the bedding. The timing means she passed 3 'eggs' [as in ovulation-wise, yolks of some sort] in a 12 hour period. I'm so incredibly worried about her and nothing I've found online is giving me answers. Why would she pass 3 yolks so quickly? I can't get into a vet until later tomorrow so any insight would help me, thanks so much..
