I may need some help here. I went out to check on the chooks around noon, and noticed one of the 5 month old BC Marans pullets standing off by herself, fluffed up. It was a fairly warm day, 50s, but cloudy and damp. Got her in the coop to inspect her, thought maybe crop was looking a bit larger than normal. Felt the crop, and while it was full, it was not hard. She didn't seem to have any problems running to get away from me, but when she stopped, she went back to the fluffed ball-like posture. Looked to me, just watching her like she had a belly ache. I did worm all of them with Wazine 17 on Monday, and all others are fine. She was fine this morning, but by noon looked like this. She is the only one that the dirty old man Fuglee roo has been breeding for like the last 2 weeks on a regular basis. Her stomach and vent did not appear to be hard, nor could I feel an egg. I've never had to deal with a sick chicken, so I'm at a loss here. She was eating, drinking, and pooping earlier today. I brought her in the house and put a lamp at one end of the cage for her, and she seems to be appreciating the warmth. I gave her a squirt of vitamins/electrolytes, and a squirt of olive oil in case it may be her crop, and massaged it for a while. She has access to vit/electrolyte water, and feed, but so far she's just laying down getting warm. Any suggestions here?? Will go to town in the morning for some yogurt, antibiotics, and anything else you folks can come up with. Of course this would happen when nothing is in the house! Any help would be appreciated!!
