hello -hoping for some advice. we have a hen about 1 1/2 years old; up until today, she was acting normal, eating, pooping, etc. today, she is drinking, not eating and just kinda standing around, somewhat lethargic. I checked her crop which did not feel unusually hard or squishy and also checked for egg bound issues. there is no foul odor or other issues. she is just standing around, not moving much and is now roosting which is very odd as we are about 3 hours from dusk. I have spent time today reading and trying to narrow down what is happening but I am at a loss; any suggestions?
