it is nice to see them back and if they've got anything about them they'll turn up.
A fancier from Carmarthen was suposed to collect 1 from here last monday, still waiting!
its time to accept you will prob never see them again!
Sorry reality check, either killed or just flown away and dropped when exhausted, possibly just not good enough or they'd have found there way home.
maybe before actualy sending a bird to an avian vet then send droppings and swabs for testing as this would be a lot cheaper than sending a bird and may give you the results you need to be able to administer the correct medication.
Welcome.
Its not only the distance you need to check with your local council but you also need to check for covenents on the proporty prohibiting the keeping of pigeon/poultry.
unless the red cock carries the yellow gene you will not breed any yellows. The sons of the pair will cary yellow so by then pairing a son back to its mother will produce about 25% yellow
if they have access to it during the day and you let them out through it they will soon find there way back in. I let my yb's out of the open door but once they are flying and training starts they have to trap through the sputnik or go hungry. They soon learn.
this is a link to result from training toss so must have been in the basket.
