Yesterday my hen Tinkerbell and RSL (not sure on age) started throwing up. I honestly thought she had diarreah because it was runny and brown. But it came out the mouth. So I figured maybe it was from the heat, I get nauseas when its really hot. hen I went out there again later yesterday and everyone was fine. So today I go out there as usual and she throws up a whole bunch of water she had just drank. Then of course all the other chickens run over to eat it. Is it just because of the heat or am I missing something? They all are wormed. She acts completely normal otherwise. Oh I don't cull if thats a suggestion to fix the problem Thanks
I didn't think chickens could vomit! However, your first line of enquiry should be whether she's got an impacted crop or not, then take it from there. I do often find my hens 'vomiting' water after having had a huge drink but not letting it all get down to the crop before putting their head back down to peck at the ground, but true vomiting in a chicken is a new one on me, sorry.
It was mostly water. Her crop seems fine...I don't know what would an impacted crop look like? Her's is normal size like you don't even notice it.
