Alas, I am unable to get hubby to budge on an incubator larger than the two I have now (hatch in one, incubate in the other), especially a big one (it would be so,much.fun!!). He did point out we don't really have a place to set up a large cabinet incubator full-time. Sometimes the man has some sense.
He is looking askance at a way I could possibly add 20 to the 40 or so I can already incubate in one styrofoam incubator and get 60 chicks (hooray!) but he still might relent there to shut me up....I pointed out I might do way better with shipped eggs with a Brinsea (or Dickey...sigh) and stop wasting money to get one or two chicks (or none). I mentioned it's time to build a chicken barn so I could hatch and brood outside instead of the dining room (and I would have space for a big incubator...mwhahahaha) and he glared at me
He helped me with Stupid this evening, who foolishly hopped up on top the coop which makes him very easy to catch, and when he held and I spread, I see a small feather growing in!! It's just very slow. So he gets a stay of execution for now while I watch and make sure it comes in properly.
Wasp might not...he actually connected with hubby (wearing a red shirt) and left a scratch in his shin this evening. Even though DH says to not kill him, I might process Wasp with the meaties (assuming I can catch him...he is wild.)
