Hello! I am new to chicken keeping. I have 4 Americunas (15 weeks old) that have been in their new run and coop for a week. I have 2 Lavendar orpingtons (pretty sure one is a roo) that are 8 weeks old I want to add to my flock. Would it be safe to put the Orpingtons in a wire dog kennel inside the run for a week or so everyone can get used to each other? I was a little concerned about chicken necks and those openings on the kennel? Also, would they be safe to sleep with it in there if it is on the ground (grass in there right now). Our temps are 50’s at night (will be getting down yo 49 one night) for a few days then back up to the 60’s. I’m wondering if there’s anything I need to know like make sure they have a way to get up off the grass, etc. I will put a tarp over most of it at night so they feel safe and to block wind. Thank you for any help!
