Alright so this week, my white leghorn has been getting very 'poofy' looking... At first I thought she just needed to lay a big egg or something. But she didn't lay an egg, in fact, she hasn't laid an egg all week! She is very POOFED OUT! I mean, like a marshmallow! She doesn't sleep on the roost anymore, she hardly eats or drinks and she stays away from the rest of the hens-very secluded. Her comb is also starting to get a purple tint to it. Just a few minutes ago, I relocated her to a large dog crate with food and water and I hope for the best. Please someone needs to help me I don't want her to die!
