If you were able to tube feed him, he would have food in his system and start pooping, then we could analyze his poop and possibly rule out some things or maybe start him on some type of medication(s).
Look casportpony is correct in saying that the best way to get them back up to fighting weight is by doing the tube feeding. Now that said....I am a coward when it comes to that. I am so afraid I will put things in the wrong place I just can't do it! What I have done is take Sav-a-Chick and mix it 1 envelope to 1 qt. and 'feed' it to my birds a drop at a time. 3-4 times a day. Either by dripping it on top of their beak or getting them to open up and doing it that way. I am always very careful not to overload them as I don't want them to aspirated. Most times, this is enough to get them the vitamins they need to get their own bodies working somewhat normally, so they will eat themselves. It is labor intensive and you have to commit yourself to it. Once you have them eating and drinking on their own, well, since you know these birds are having an issue, I would add a showbird crumble or a game bird food with a higher fat and protien level. You could mix this right into their normal feed, or give it to them for a bit to help them get to where they should be. You also could take this same feed and mix a thin gruel out of it and do the same drop by drop. Once you have them close to normal weight, you've bought yourself time to find out what is going on. It's either this or cull. You really don't have too many options here. 1.4 onces is something, but you need to keep it going up. You've done so much, that it would be a real shame to have it all go south now. You can do this, take a breath and figure out what works for you and your birds. Then go with it.ok, his weight went up! it is now 2 pounds 6.4 oz. it was 2 pounds 5 oz
