I have 2 pens of seramas. One pen is primarily smooth, but carrying silkied genes. The other pen is mostly silkied, with a couple smooth girls. I've lost count of actually how many I have right now. 30ish I think lol. (5 new ones just hatched in the last couple of days, one egg left to go!)
Some are friendly, some are very skittish. Mine sleep outside, up on high perches in their run, even through winter. Most of my girls that are old enough have raised at least one brood. They wean their young within 5-6 weeks and are usually laying again by 7 weeks from hatch. All my boys get along together, well, that is the ones that were raised together. The girls rule and the boys do as they say! Lol. My oldest rooster has been extremely good with babies, and training the younger boys.
Oh, as far as hatching them....I normally give 24 hours from pip before assisting any other of my breeds, but seramas can be a little weaker, and I've started assisting them around 16-18 hours after pip now. Much more successful, and less DIS losses.
If i think of anything else useful, I'll be back!
