I just lost a 22 week old pullet. I came out a few hours ago to notice she was not free ranging with her two friends like she normally does but instead she was inside her coop breathing hard. I separated her into a smaller pen with fresh water and food thinking she just needed some space and fresh water since she gets bullied by my older hens. I came out 45 mins ago to find her laying on her side breathing very hard. I picked her up and she squealed and started convulsing. She then just died in my arms. I am heart broken. The reason I question infectious bronchitis is because I have some (not all of them) 1 year old pullets that are laying eggs but their whites of their eggs are a bit runny...So much that when I break them into a skillet they will sometimes even separate from the yolk. But I have not noticed any breathing issues or coughing from them. Could these two things be related or separate issues? What would you do?! I do not know of any vets nearby that take care of chickens.
