I am curious if it is normal behavior for my birds to be huddling together on the floor in the smallest of spaces at night. They have a lovely coop with two big windows and it seems that they are trying to get as far from the windows as possible. They don't roost, they crowd together on the floor right in front of the door. Is it possible that they dislike the windows? The coop is not drafty and it makes no difference whether their heat lamp is left on or not, so I don't think that it is temp. related. Same spot every night. Just basically wondering if we have made a mistake by putting two big windows on either side of the coop on the end where their roosts are. Anyone seen the same behavior?
