Well, I am happy to report that just a few minutes ago the neighbor dad showed up with 2 replacement Rhode Island Reds. I guess he raises chickens too, from what he told my son. We are both feeling less angry. How do you think these 4 will get along? the new ones are about a week younger....well, size-wise they are smaller, but feather growth-wise they look about the same or ahead or ours. Maybe they are just smaller than ours.
Ours are about a month old. maybe 5 weeks.
Thanks again for all your support and empathy.
