I woke up this morning to smoke my morning cigarette and was shocked to find a pigeon sitting on my bottom step. He is responsive but would not move. When my dad woke up I asked him what I should do because as a child we attempted nursing a bird back to health and it unfortunately died. My dad tried petting him and we realized his leg was caught in a crack in the brick. when my dad released his foot he semi flew to the side walk and didn't move from there. we walked over to him and he hobbled as if he had a broken leg. My dad grabbed him and I found a cat carrier and a towel and we placed him in there. My dad said he looks like he has ticks very very large ones that hid under his feathers. I have a 9 month old son and two cats and a dog that I am scared to bring him in if he has something that could hurt them. I don't want to call the humane society because I am sure they will kill him. I would like to see him healthy and free. Not sure what to do and I don't have much money to work with. I have read many posts but still am unsure. Please help. He is responsive but I think he is sleepy cause he has the towel over him and he looks like he is trying to take a nap but becomes alert at any sound. any advice is welcome.
