My RIR runt was the sweetest girl - smart, friendly, and a great layer.
Cuckoo Marans have been great - sweet, easygoing with flock, beautiful eggs and very productive
My BAs are a little flighty, tend to be at the top of the pecking order, and not so nice to younger chicks. Super pretty pink eggs
EEs - Love them. Smart, some really friendly, including our Roo, and GREAT Eggs
S. Sussexs great foragers, a bit broody, good mama hens, good layers, some super friendly, all pretty calm, fairly sharp
BOs, broody, good Mama's, good layers, pretty friendly. Not very bright...
Three broody hens (BO, EE, S.Sussex) hatched out 16 chicks, and we picked up 2 each: day old Wellies, Salmon Faverols, and Wyandotte which the EE hen readily accepted, so we'll get to see how those breeds behave too. A little concerned our socialization isn't going well because the mama hens drive them off at around 10 weeks and the rest of the flock won't let them get too close to us - even when we have no treats.
We use pretty extreme integration, in the coop with minimal segregation from day 1 under mamas protection (til they aren't), a couple of lower out if the way roost bars (in the main coop) though some have claimed spots on the main roosting bars already, and food and water tucked into out of the way corners to ensure they're getting a quality diet to supplement their foraging.
