Pigeons and crows usually go into my chicken run to eat the chicken feed however i was walking to go close the coop door at night and a pigeon starts going crazy trying to get out so i go back out and wait, but its just not getting out so i finally go in and its on the floor and it does not fly away not even when i touch it or pat its head and not even when i pick it up. After seeing if it was hurt or not i let the pigeon/ dove go fly but it doesnt fly so i kinda throw it ( not harshly) and it ends of flying away this was a precious moment for me but what is the reason for this wild bird to be so tame?
