This morning I went to let my girls out, and my Mille Fluer Bantam didn't run out with the flock. She was still roosting and essentially limp. I picked her up, and her head was floppy. She was coo'ing. She is normally not one to be held. She gave no resistance and acted like she couldn't control her neck. I brought her inside immediately and put her in our hospital room. At first she wouldn't move minus her neck flopping. But she has tried to get up and move sometimes with success and sometimes just to fall over. I gave her water with electrolytes. It's been hot the last few days though she has had access to water. I gave her plenty of food (Scratch and Peck). And I recently put in a soupy egg in a dish for her. I watched her eat the S&P. I dipped her beak in the water and egg. She is still coo'ing and attempts to move. Sometimes she looks fine. Other information about her is that she is about a year old and laying. It appears that she laid at least yesterday if not today. My boyfriend normally collects the eggs so I am not really sure if this egg was from yesterday. I smelled her breath, it's not sour. Her crop isn't full. She was fine yesterday. I'm at a loss.
I had a few cases like that. they are very weak till they lay an egg. then they return to normal.
make sure she drinks. you can syringe some water if she doesn't. you can give her aspirin as well. check for dosage.
