You keep doing 'chicken math' you're going to have to expand.
I am at 44 not counting the new hatches, which isn't bad since most are babies or bantams..one point I was at over 100 because I was doing so much hatching. Out of the 44, about 14 are for sale or destined for freezer camp. I have 10 in the incubator but I'm going to resist "counting my chickens before they hatch".
I figure with 15 shipped eggs I'll hatch about 7, 4 of which will be boys, so that leaves me 3 girls to pick the best two from. The boys will go in the freezer.
I think I can manage to stay in the range of 40-50 if I can resist impulse buys and wanting to keep what my broodies hatch
