I have only needed a pen once and it wouldn't work where my broody was, but she was just too mellow so no babies for her.
I have had SOOOOO many broodies this year! at one point I had 4 at one time! LOL but adding them all up (some broody 2-3 times) I would guess I am at at least 12 total times broody so far for all my girls if not more since many times I had 2-3 at a time and would break one and another would start..... I have 15 girls that lay (17 total adults but 1 has never laid and 1 very rarely lays so I don't count them) and most of the summer I am getting 5-8 eggs a day which is pretty sad for this many girls but they won't stop being broody! LOL
I am DONE hatching for the year. I hatched in March, April, twice in May, (sort of 3 times since June hatched started May 31. LOL), June, July and Aug! YIKES!!!!!!!!! My youngest just hatched the end of last week and I have 12 of them, then have 4 that are about 3 weeks old in my coop brooder. Most of the other groups I only have the ones I am keeping besides my 9-10 week olds that I am still trying to figure out pullet or cockerel. and 2 roos I still need to find homes for. LOL
