Ill post my chicken bomb when i find the picture. # day olds on a nice big old 12/0 circle hook. Personally i do not believe in leaving the skin on, or the wings head and feet. Reason behind taking off these parts is hook obstruction. I've snagged a wing and what not more times than i care to mention. For me leaving the skin on and making it look natural will work, but for me the way the barbel hones in on its prey this is not neccessary. When skuim floats the bait, yes in clear water you will need it to look natural, as the barbel is using sight to find its prey. But in dirty water i cast a skinned day old under a tree and they hit it almost as it lands using the vibration from the bird landing to find its food. In looking and researching different catfish species over the years certain trends pop out, mainly when we look at the eyes, a catfish like the piriaba of the amazon or the phemba in the congo they use sight to hunt, whiskers are short. Our barbel has small eys and over developed whiskers, along with the fact the skin is loaded with taste receptors our barbel are mainly finding food by smell or vibration. So i skin my day old especially because of this. If you look closely at the day old when you skin it, you will see fat under the skin. What is fat made up of? Most importantly what is the catfish looking for in its prey? PROTEIN PROTEIN PROTEIN. So just by taking of the skin we put a scent in the water off the fat. But the biggest scent from a day old is from blood and the egg sack. By removing the head of the bird i open up a cavity down its neck into the organ cavity, this means lots of blood once it defrosts and also scent from the guts and organs. When we cut open the stomach you release the egg yolk from the bird, this is the embriotic sack that it feeds on while growing in the egg. This is loaded with protein and is an amazing way to get scent into the water. This is also a reason i sking the bird. I personally believe this part if the bird is a semi permeable membrane. This has been proven to me time and time again when small fish or eels are present in my fishing area. Ever had a tug on a day old and than nothing? Every single day old i have a small run on that i have taken out the water has had the egg yolk or stomach removed. The fish ate the egg yolk and than left the rest of the bird alone. It used its highly developed smell and scent receptors to find where on the bird the tasty smell of protein was coming from, removed it and went off. So this tells me the fish could smell the egg sack. It was releasing scent and the fish followed that scent trail to the source. So this brings me back to skinning it and why i disagree with cutting open the stomach. I can create a scent trail by removing the head and skin, and can than create a scent trail that will last for hours by leaving the stomach intact. Immediate scent with blood and fat and a slow gradual scent with the stomach. If i open the stomach i think we release to much scent to soon. Once its gone, its gone. As it sinks the egg yolf will leave the body, even while you cast it will fall out. So most of that good scent never ends up where you want it and is gone very quickly after the bird lands in the water. This will be great if there are fish really close to your bait, but if you dont have them close than you need to rely on scent being spread around, ad you need that fish to follow the scent to your bait. If all that yolk has left the body and is not close to the bird leading the fish there like a road than you will miss fish and also your bite rate will decrease rapidly. If fishing in current you will be sunk before you start as all the scent will wash down stream with no connection to the bait. In a bomb i will cut open one of the 3 day olds i use to create that huge initial scent trail in the water. But i leave the other ones as i want the slow relases and trial to last.
Anyway just my 2 cence. Will try post my bomb today.
