My leghorn 1-2 weeks old(was on sale at TS) has a puffed up crop she moves her head around like a snake charmer. We got her this past Friday and I noticed this Saturday. I started the sav a chick probiotic sat night. today I picked up duramycin-10, poly vi sol, and apple cider vinegar and put it in the mix. She eats and poos and drinks water. should I worry or do you think it will take care of it's self? Here's some pics I took today. I also bought olive oil yet to give her any. and she only eats starter chick food cept maybe a pine shavings. last pic is of her poo just incase it may need to look different. tip was hard then rest soft almost liquidy.
