As of now the access point is the hardware cloth. Perhaps they'll be out by the time they are out the second hen hatches. I do have 4 young birds (2 each) in that situation. The 4 keep to themselves so it MAY not be an issue. Momma is pretty good with me as you can see but I don't know how she'll do with the others when they come out. This will be interesting. You say not more than 2 weeks? That was a question I was going to ask. Thank you for that and the feedback.Saw your video. Pretty nice set up for temporary quarters. I'm wondering though, where is your access point? At the hardware cloth?
Apparently you have a hen hatching out your chicks? Hopefully she is fiercely protective of them. I wouldn't keep them separated any longer than absolutely necessary, say maybe 2 weeks at the most. Just long enough to be sure they're eating and drinking well and know where their food/water supply is. With the hen to protect them, you can let them mix among the flock... it will go better for the chicks. I'd watch older flock members, particularly other young birds if you have them... say a young cockerel coming into sexual maturity just might decide he doesn't like the chicks and might go after them. I had that issue here last week as a young cockerel who was only alive to get to butchering weight decided he didn't like some chicks and treated them poorly. It was only about 2-3 weeks before I had intended to dispatch him but I moved it up as he was disrupting the flock altogether and the older boys had taken to running him off the food too and I didn't want him to be tough eating so I did the deed early. Now, all is peaceful again and the chicks are free to move around without being harassed.
