Put the four in a basket and fast for 24hrs, if their crops are clear after this put them back in the loft. You will have to keep a keen eye out for these after as the likes of e-coli could take advantage of them being a bit down especially as you'll be putting them back with older pigeons.
Whatever the problem is its effecting the digestive system big time. I've seen droppings like this with a pigeon that was infested with worms also seen an egg bound hen with similar droppings. I wouldn't like to hazard a guess as to what the problem is here,
I think there's a few factors involved billt. As stated we down here are not plagued by hawks which must be the main factor. I basket up my youngsters at first light and train whilst most are still in bed = clear skies. Our race controller is A1. Where I live the river Thames is a couple of miles behind me and believe this acts as a natural barrier (if they overfly my loft and hit that they're reluctant to cross)
Lost 6 settling them in round the loft. 3 never made the grade Started training 42 Lost 1 training Lost 1 racing After 6 races and umpteen training tosses still have 40 N.B. Very little in the way of hawk activity down here in the South East
For new starters in the game box perches, simply because its easier to pick up the pigeons from these. My preference is the slope back perches/ lift of perches, they dont stand in their own droppings with these and they're easy to clean.
I fly the w/hood system in the main, If I found myself in the position where my yearlings were only trained as babies and not raced I would send them sitting eggs for their first couple of races. My thoughts are I wouldn't want them wound up too much to start with.
