Hi All, My chicks are now 5 weeks old. I have been trying to stay ahead of their growth to finish my coop and run. The run has eight foot fencing and I opened up the entrance using a dog door. Finally, I added the ramp. It was a good day (no wind and clear sky), so I grabbed the camcorder, opened up the door and waited. The chicks are very inquisitive, but apprehensive. It took a while for one to venture out. Others followed. Looking at the coop with the man door and chicken door. I have RIR and Buff Orphington chicks. These are the first to try the run. While taping, I followed the RIR chick as she was chirping. Panning across the ramp, I noticed something: The chick went through the fence! I had my dogs in the house (thank goodness). The coop and run are in our backyard courtyard. Needless to say, I rounded up the chicks that were outside and placed the cover back onto the dog door. I will line the run with chicken wire, which I have. Step back and proceed with caution! This is my warning to anyone who would try the same thing. I thought I had chickens, but they are still chicks. (I captured the still images from my video.) Dick. Phelan, CA.
