Hi everyone, Seems like my chickens are always sick these days. Anyways my white plymouth rock hen has been walking really funny. like her butt down almost touching the ground like she needs to lay a egg. Not interested in treats unless I come up to her then she has some. so I picked her up and her bum felt like mush. If you have a chicken with sour crop thats what it feels like. they haven't been wormed since oct/nov. Anyone know what this could be? Thanks for your help I greatly appreciate it .
