Nest boxes have all been scrubbed out with bleach solution,all pigeons been dipped in chlorocarb and treated for canker with tricho plus before the big moult. The next thing i intend doing is worming them as ive not wormed them for about 5 years but that will be done after the moult.I also intend to try and get them out more this winter as i dont like locking them up to long it can lead to gammy wings when you do start to let them out due to being unfit and getting frightened by bops they take off at a hundred mile an hour which can cause damage to a very unfit pigeon.
