I'm sorry I gave all of you a play by play on my horrible day. I was freaking out. Still am. I don't really know what to do. So far I've lost about 30 birds. With probably 10 more sick. Some seem fine. We left to go get a defector. Im scared for the rest and my dogs, cat and Hedwig. Im afraid to go to coop. I can't figure out what it is.
I am so sorry to hear about your little ones....did you use the same feed for all of the ones who got sick? Botulism is a strong suspect if you did. If they were all fed from a new bag today I would call your vet tomorrow and ask if they know of any way for you to have the feed tested.
In the meantime... provide the surviving chicks with finely ground scrambled eggs and maybe small amounts of boiled fish, tuna, catfood or boiled chicken. Avoid anything salty.
Give them fresh water also, but clean the feeding dishes and drinkers with a mild bleach solution first.
Good luck and hope the worst is over.
