Hi Aart, hopefully I’ve added location properly, it’s Stillwater, OK. I think that summer heat is the biggest weather concern for poultry in OK, though we do get some erratic frigid weather. I looked at breeding pens but we have a fair amount of prairie available and my husband doesn’t like permeant structures on the prairieland, so I came up with the electric netting and mobile coop idea instead. My posts are always too long so this was short on details, but we currently have a 6 month EE cockerel in a coop/ run with five hens he was hatched with, plus six four month pullets, two silkie pullets, seven four month old ducks (layer breed). The six month cockerel is doing ok with the pullets (only breeding the six month pullets who have been laying fertile eggs for two months now. No feather damage after initial learning curve, just getting spurs) though he has a little roid rage first thing in the morning. I wouldn’t have kept the EE roo, but DD is attached. So plan is to shift EE roo and his five gals (who have been unpleasant to newer pullets) to electric net/mobile coop, maybe have his hens hatch eggs to add pullets to get the favored 10 hens:roo. There is also a Newest batch of six, one month old chicks, that has a BCM roo and CCL pullets for breeding olive Eggers, and will be moved to coop with current 4 mo old pullets when EE and his gals move out. So, we have some idea of how obnoxious roosters can be, but I am keeping an eye on the Situation for DD and pullet safety. We plan to set the E Frisian Gull cockerel (Lemonhead) up with the electric netting/mobile coop and E Frisian Gull pulllets, but only have one gull pullet right now. Lemonhead is currently in a 4x8’ tractor with silkie cockerel, as EE roo acted like he was going to kill the two cockerels, plus Lemonhead was obnoxious to pullets. EF Gulls “don’t bear confinement well”, so I think that this setup can’t last too long. We’d like to “warehouse” the EF Gull cockerel for now, until we can get those EF Gull pullets in spring and put them together late summer. We do know that hatching eggs yields cockerels ;-). We’ve hatched multiple rounds of eggs this year and rehomed many cockerels (we’ve been lucky, I know, but I think that a lot of Oklahomans free range large groups of hens with numerous cockerels/roosters who end up as hawk bait, so I’ve been able to place all on Craigslist). If need be, I think we would consider eating extra Roos also. DD likes them but is at least somewhat selective! Anyway, I’m trying to support DD’s new hobby without taking over, which I’ve found incredibly difficult since I’m kind of an OCD animal lover and project planner myself!
