Three hens why only an egg every other day?

[Me + Peeps]

I have three hens that i purchased and they are 8-9 months old but why am i getting only one egg every other day? is it possible two aren't laying yet? could some chickens never lay an egg?

Mine are slow due to the heat. If you just bought them they may need time to adjust to the move.

I've had them for two weeks and they eat out of my hand so i think they should be adjusted

I just gave away 2 RIR 8/9 that didn't start to lay yet (I have had ones that didn't till 10 months)
