I have raised baby chicks from hatching my own eggs. You will always have too many roosters, and they can be hard to give away or rehome. Usually in a smaller flock, only one rooster is best. I have kept 2 or 3 in a flock temporarily, but they need to be docile, and the younger ones need to...
Well, that is a problem with having more than one cockerel or rooster in a flock. How many hens do you have? It might be time to separate them, and decide which one you will keep. Some people will keep one rooster in a bachelor pen, and rotate them in and out at intervals.
The Powerade is good, water with sugar, or plain water if he doesn’t like the Powerade. But he could use the electrolytes. Here is a video on tube feeding:
For just fluids and not food, a piece of aquarium air tubing is good, and it will connect to a feed store 35 ml syringe. Raw egg and...
Do you have a straw or pipthe where you can draw some fluids up and drop them inside his beak a drop or two at a time? Otherwise I don’t think he will make it. A vet could give him fluids through a needle under his skin, or you could try to tube feed him.
Does he seem skinny to you? Could he have been prevented from eating or drinking by other birds? His comb is darker on the tips, another sign of dehydration. Make sure to have multiple feeders and waterers around the area where they spend their days.
Just get him drinking the Powerade, as much as you can get into him. It has sugar and electrolytes that can help revive him if he has heat exhaustion or dehydration. Make sure he drinks enough before offering him food. Mushy watery chicken feed and scrambled egg or tuna would be good. Dry feed...
How hot is it there? Could he have heatstroke? Maybe dehydration? Can you dip his beak into water for a half second, and repeat to get him drinking? Use a dropper to place it near his beak if needed. Do you have any Poultry NutriDrench or electrolytes? Gatorade, Pedialyte, SaveAChick work well...
