Their wings are able to lift them off the ground but not to reach very far when I let them out free to roam about the yard, Also My doves mostly Always cooed when I got them for first 4 months, but after a while they stopped, they just got bored and rarely coos, The male coos the average ringneck dove coo, while the other male dove IS know where near or close to the other male ringneck dove coo<<<His coo is sooo different and I thought that would of been the female but so many months past and no eggs in the cage so both of them are males and the female I got coo is weaker than the average male coo, its just hers is like a lazy coo or just weaker but still is very similar to the 1st ringneck dove coo, but all of them rarely even coo, its like every 3 days one will coo, then other will coo another time and then the other? Idk whats up, idk whats happening to them, They are active and let out the cage everyday to roam and fly on trees?
