I think there's 2 things I need to do to make more chickens a possibility. One is easier than the other. I need another high roost. I have 3 roosts (low, mid and high) and right now, 6 roost high and 6 roost mid. I think I need another high roost and since my coop is tall enough to walk in, there's no reason NOT to make use of that space up there. Plus, more chickens up high means less chickens getting pooped on. LOL!!!
The 2nd is I need to get the puppies their chicken merit badges so that I don't have to keep timesharing the yard between chickens and puppies. Because I have to keep them in the run so the puppies can be in the yard, they don't get as much free range time as I'd like. If I could trust the puppies, I can let the hens play outside most of the day so the size of their run would be less of an issue.
But the more I see chicks, the more I am thinking I'll let Mille sit on some fake eggs for a while and then slip day old chicks under her at night instead of having her hatch them.
