This has just been posted on another site by Greg Large.Any opinions please ? "Often hear of extreme losses and experienced some myself in past seasons, but I think very often youngsters have YBS and are suffering without it been seen. I have 2 sections, last week one lot started playing up, so kept them home rested and fed light,no race last week for that section, sent the others. Then this week the second section had a bad trainer, and I got suspicious. I spoke to a few fanciers and decided to push them, and see if they show anything, and I got a bit more suspicious when they were not listening as normal. Just one or two not responding normally would pass it off as them having too much corn the night before. Locked them down last night, and they look like never before, top condition,silk pink of condition, lively. And theres the thing, at this point me just a year ago and sure many many others would send them expecting big things from the race, BUT they ill, and I know now big losses would follow, Regardless of how they look. Its this deception that gets many, many fanciers. There are no symptoms at all. Heres the subtle indications I saw, first on basketing for trainer in morning 3 of the 20 had a little corn in crops, not alarming subtle and surprised I noticed. Not bulging crops but 3 grains or so. Then the trainer they came scattered, compared with the other section, all made it home and most weeks would think falcon struck em, but suspicions rose. Cleaned all perches, went in at night with torch, no corn thrown up, but one oil green dropping. Sent training yesterday to make up final decisions and dropped 2. Then I knew as I don't drop them training,they had tens of communal trainers and not dropped 1 till yesterday. Had that not happened I would think they perfect. In Hindsight the one oil green dropping should have been enough, and I would have saved loosing two for no fault of there own. But I have had last year one getting Ecoli when the rest were perfect, and this was in the back of my mind. It takes experience and observation to see they have the virus and there brains are not functioning as they should. I am normally not observant at all, but little suspicions added up. Hope someone can take something from this post, You need to watch them very closely and often when they look there absolute best, they could be very sick. This I think contributes to many of the unexplained losses we hear of. Old birds are different, they don't look like diamonds when they ill, they look sick and loose condition and shine very quickly." ATB Greg
