I have 4 mo old guineas. They free range during the day and I have been feeding them only at night to get them to come in to be safe. (I lost 9 in one night when they stayed out) They have been doing great until just 2 nights ago. I had to catch them to put them inside. Last night I waited until almost dark to see what they would do (roost, come in or ?) They remained in the field in a little group. I ended up herding them into the barn and let them stay in a stall. Grrrrr. I don't want to go through this every night but I don't want to loose more birds. They don't have a fenced area that I can just leave them in. I was also wondering if the coop was too hot (even tho I open it up to cool it down, leaving the windows and vent open at night) Any suggestions?
