I had a pet rooster that grew up IN my house from the time it was a lovely yellow chick. As he got very big, and it was pooing everywhere, we had to get rid of it, (We were living in an apartment). However it was a pain to be separated from it, as it was very friendly with us. It had never attacked anybody even from our visiting friends.
We sent it to a close village at my husband's relatives, (and we got promised that they would not kill it), hoping to see it sometimes when we go visit them. As it changed its environment, it had become very aggressive, especially more aggressive towards the children. It was very painful to me to know that he was put in the cook pot.
