Yep, hot weather will slow up any hen...wow, never heard of them pushing the eggs out before! The 2 you got in March are probably close, I got 4 in March and 2 of them are laying currently.I have 4 RIRs and got 2 in March and 2 in April. I have put golf balls in the laying boxes and find that they push them out and bury them in the coop. Still no eggs that I can find. I let them out during the day for a bit but keep an eye on them. Been hot and humid here in Ga so not sure if that is slowing things up or what.
