Widowhood are flying back to get to their mates aren't they when they see them on basket day? Pouters are going out finding a mate, I'd be interested to see if you left a racing loft open would the cocks go and find their own hens.
It depends what your wanting them for mate, if you just want to watch them fly ut then any pigeon shed or kit box will do. If your after trying to catch other pigeons they need to be kept solitary so they are desperate for a jump and them you need a trap or box fir them to work to trying to lure other birds back into.
Thats a young feral cross bird I've caught a few ferals and racers with this year.
Because they are all crazy eyed manky grizzle things mate, they have all different strains though and some go for silly money.
They compete with them the same way as tipplers I think seeing who's will fly the longest, I think some can fly 18 hours.
Have they said it was a bull breed? I don't think they should be bringing in the feral street dogs from other countries either, mutts that have had to fight for food all their lives and live on their instincts are no good round kids that will try and take stuff off them. No dog should be left alone with kids though.
