Hi everybody, whats wrong with my pullet? She is straining in her vent, she is listless, her comb/wattles are pale, she won't eat or drink, yesterday she laid a yolk- thats all, no shell. I looked at her vent earlier and she was acting like she was trying to lay an egg. And i saw a mite type of bug crawled in her vent. Could it be egg binding? I don't know what to do, any info would be really appreciated.
