My sex link has been egg bound for 4 days. She is approximately a year and a half old. She lays an egg every day, but 4 days ago she became lethargic and stopped pooping and laying eggs. I witnessed her excrete some nasty white stuff. She eats and drinks very very very little. I have soaked her butt in warm water for 2 sessions of 45 minutes. She just doesn't seem to be getting better. She's my very favorite hen and the sweetest one, too. How can I save her? I'm up for anything at this point.
