Good morning, I hatched 2 emu's early spring this year. They have been doing great up until now. I was ordering in their food thru the feed supplier in my town and she was unable to get it as the warehouse burned down so she switched me to a different feed ( game feed) with equivalent percentages. After a few days on the feed my older bird started to sit more, not eat and was having loose stool. The vets in my area aren't knowledgeable on emu care but I did find one in another part of the state that was. She advised me to treat with an antibiotic and keep trying to get feed in. Now yesterday I spoke with someone that raised them years ago and she said she is 90% sure from what I told her that by feeding that substitute food which was crumbles instead of pellets caused them to have an impacted gizzard. I am at a loss to know what to do and feel very helpless. They are both off feed and water now. I have been trying to get mineral oil into them but not sure I am doing enough or if that's even the answer. If anyone has any suggestions or experience please share. I feel so helpless and guilty that I did this even though it was unintentional. I feel horrible and I so love these birds. Thank you for taking some time out if you have any ideas to share.
