We bought 4 chiks on July 8th. 2 Barred Rocks and 2 GLW. LAST night I noticed one of the BR not doing very well. Unfortunately, she didn't make it through the night. I'm going to change all of the beddding, water and food dishes, and I've placed the deceased chik in a tuber ware container because I read a post saying I should have a necropsy done. Is there anything else that needs to be done? Where and how much does a necropsy cost?We're new to raising chickens so all info is appreciated. Thanks for your help?
