Rooster looks like he’s going to die tonight. Pesticide poisoning?!

I checked that first thing, I wish it was that because I’d know more what to do to help. His crop is fine. Had problems with it in the past but easy fix. This is much worse I just checked him and it looks like he vomited on his chest and he is just so uncomfortable

If he was in the heat with no access to shade or water he could be suffering from severe dehydration which is life threatening. Eating dry feed without drinking water could cause his crop to become impacted causing a blockage( comes back up )Being unresponsive is one of the signs of being dehydrated. Chickens with loose poops are more easily dehydrated.

So, I'm not very good at breed identification, but is he a CornishX?

I’m sorry. First post. He’s only 3 months old. Healthy all day. Gave him cucumber skin scraps and then so sick. All the other chicks are fine tho and they ate them too. Possibly pesticides? I didn’t wash, but they’re organic? He won’t eat or drink. Bedding is hay, feed is still starter- organic non gmo corn free. I’ve tried giving acv and garlic but unsuccessful. Today was a hot day and I noticed the water tipped/emptied, so maybe a half day without water. His poops have been runny which is his normal as my toddlers wont stop feeding food scraps and he is the food hog/twice as big as all the other same age hens. Symptoms are :lethargic, wide open mouth, no food or drinking, wont get up to roost, looks so scared and confused. Won’t even eat his favorite treat

I agree with @RubelliteRose and @Lenny loves chickens it looks like he's a meat bird (CornishX)

You mention that it was very hot and they ran out of water. CornishX seem to be sensitive to overheating and they require a constant supply of water.

Sadly, at 3 months of age, he may be near the end. He may have suffered a heart attack or his legs are just no longer able to hold him up.
If he suffered heat exposure, you can try to see if he can rally, but he needs to be moved to somewhere cooler and provided with electrolytes. Fluids first! I'd get fluids into him then see how he is.

Very unlikely it was the cucumber since all the rest of the birds are fine.

Oh, he's a hog because that's what he was bred to be. CornishX are meant to eat like pigs, gain weight rapidly and be processed at around 8-12 weeks of age.
I'm sorry.
